The Phantom Menace -Theatrical Version - NTSC DVD- ADYWAN - NOW AVAILABLE
Time

The Dolby Digital 6.1 Ex soundtrack for Tpm laserdisc is one of the best ever put on laserdisc, straight from the theatrical master. Most of the audiophiles who know used high end equipment to demodulate and decode it. Dvd is another story because its all digital and dont change much from one player to another leaving little room for difference. It is the same story with mission impossible wich i checked myself, the laserdisc got more of a cinema feel to it. Lack of reauthoring and compressing the tracks again for dvd is the likely culprit.

Guessin' he meant specs . . .
btw I'm enjoyin' all your tech talk and I'm sure others are soaking it up eagerly too.
I'm glad you started this thread sooner, and didn't wait until you'd got the whole kit assembled.

Sorry if you've already mentioned in one of your 'specs speeches' in the other thread
but have you hot-rodded your players analog audio section and/or CX decoder?
Do you expect your Hercules will have much cleaner audio signal than for example Elite'97 ?

And before I officially announce my project to capture ESB'80 soundtrack,
can you tell us how badly my V8000's analog CX decoder is compromised by its industrial design goals?
How does it stack up agaist others in the consumer lineup wrt analog audio ?

The audio section is one of the better features of this player, its own r-core transformer and exotic capacitors etc. It will sound a bit better but the Cld-97 is one of the best Pioneer made in that regard, so its not night and day. One of the reasons McIntosh labeled their own player from a Cld-97. The audio section in the V8000 is baseline spec, no special capacitors and seperate power system. If you changed all the caps with panasonic Fm or fc and built your own power supply for it after checking dc voltage input on the card or section. That could tidy up the audio a bit.

Just be lucky your not me when i get my shipment of capacitors from Germany, 140 capacitors that im going to swap out and bypass with tight tolerance film caps.

Thats right moth3r but i didnt count them since their hardware is outdated, the chips that do Rf (signal from optical head) to composite decoding are not the best. The V-8000 is one of the best in this category, but this is a pure industrial design with hard use in mind not video quality. The best of these players is Ld-1010 if you can find one in good shape, it got much of the hardware from the LD-S1. It also got a red laser to reject noise better, it plays rotten discs etc.

Dark_Jedi: I checked out your JSC project and noticed a few things, i couldnt help to notice the chroma (color) noise in some of the pictures you posted. Incase you didnt know Elite 79 is a CLD-D704 with another faceplate, a few higher end audio parts, the video circuits are exactly the same. It recombinates chroma and luma for any video output, with loss of detail and color accuracy as a side effect. Its always nice to have something to judge by tho when i start capping so best of luck with your project. The only LD players to give pure output is the X0 and the C2ex (my player) Not to get people excited but im watching the anh SE 97 set now and grinning like a little boy at how good this looks, and i havent finished all the mods yet. Capture card coming in about 2 weeks, so you can expect some material in the near future. And yes im giving the raw captures to people that want to help, im not experienced with virtualdub and premiere.

Speeches ? Ive spent the recent days modifying my gear, just now i made permanent changes to my Sony C2ex Muse highdef player. Several high def circuits is no more and cant be put back in, now it only plays back NTSC. My Runco video processor got similar treatment where i desoldered 32 connectors on the back and changed mainboard with another type with less active components, all in the name of better picture. I will post samples once i got my power filtering built, lacking a few R-core transformators (best there is for less noise) and the capture card.

Ok let me explain, most standard laserdisc players use outdated comb filters to separate chroma (color information) and luma (black and white) in the incoming signal from the optical head. Thus giving poor s-video performance, many users with newer Tv`s that incorporate an onboard 3D comb filter report less dot crawl when using composite. My player does not do this on the direct composite output, instead i feed it into a broadcast grade Video processor with TBC and Motion adaptive 3D comb filter via 75 ohm Bnc connectors.

The X0 is an awesome player, but with modding i dont think its worth it (6k$ from my contact in Japan) when my "hercules" can (most likely) beat it. Not even the X0 got such extreme powersupplies as this thing, it got the same wavelength laser, it got direct Bnc (not comb filtered) output. It doesent have the 5 ntsc decoders but my Runco Vfc-4404 got several chips that handles different luma and chroma decoding tasks.

Basis of the project is a Hi-vision (muse) laserdisc player, Sony C2ex. Reason for using it instead of a Pioneer X0 is modability and potential to beat the X0 on Ntsc material. Both are LD only, have a shorter wavelength laser than the non Muse players and direct Bnc composite video output.

My intention is to capture the original trilogy on laserdisc in the best possible quality. People wanted detailed info about what i have done and doing to it (mostly tech/modding stuff for those interested). First of all i got two players from Japan, the C2ex and one broken Mdp 999 (Both Japan only high end) 999 is 30kg overbuilt. In the design of the merged player i have made almost no compromises, Muse (hi-vision) playback has been removed permanently. Some sections of the motherboard have been desoldered in order to keep the amount of active components to a minimum to further reduce fine “mosquito” noise. The 25 pound video processor from Runco has got the same treatment, now its no longer a scaler but only 5xBnc C-video input and 1xS-video output (it had 32 more connectors before), the reason for putting it in the loop is because of its very high grade design, broadcast quality Time base correction and adaptive 3D comb filter. Back to the laserdisc player, the chassis from the Mdp 999 is very sturdy and will be the base of the player. 5 massive brass feet on a thick cast aluminium plate with two 2.5mm copper plated steel plates to further stabilize it (see picture) the rest is all copper plated. On the other hand you have the C2ex that has much more high tech hardware but doesent come close to the chassis of the 999, merge them and “Hercules” is born. Its currently under the knife so to speak till i start reassembly pending a large order of capacitors (total around 200 and silver solder) bypassed by different film capacitors for different sections of the mainboard. The best of the bunch is Vishay Mkp 1837 that will be used around the most crucial chip (laser-RF to analog composite decoding) and the optical pickup input (flat) lead. Assortment of Wima film caps for the rest of the capacitors. After its been put together its going to be dampened and shielded, c2ex came with some sheet metal shields, they will be acid dipped and coated with copper before getting back to further avoid Emi and Rf interference. Together with some chip damping and shield planes. First line of defense is a 8mm aluminium lid that came off the 999 (the thicker the better in such applications) The final chassis will consist of 3mm sandblasted aluminium plates with copper sheets in between, however i dont anticipate to finish the whole chassis before i start capturing. The power filtering system will sit in the 999 chassis while the c2ex can operate fine on its own. Several powersupplies will find use in the player, some from broadcast equipment with very low dc noise output. The stock powersupply is disassembled waiting for new premium caps and mkp10 bypass. The acceptable quality OT movies only exsist on LD and a few numbers of deteriorating prints. Even the LDs dont have eternal life, so im going to do all in my power to get the best captures possible. I Heard Arine.D talking about rainbowing on the JSC discs, that is good news to me because it means there is resolution potential on those discs when they rainbow on an X-9.

Had my eye on the Special Collection, especially since it was a fresh transfer (back then) without any noise reduction. You need some unearthly equipment to get something nice out of it tho, the "V8" team spoke of a noisy image and haloing. The first is in part due to the simple compromise design of the player for very long lasting use, overbuilt but not in a videophile way. One common powersupply for the entire unit etc. Also no broadcast grade Tbc correction. The second is bnc - rca impedance mismatch, and the simple wiring to the bnc connectors on the player. Thats the way it is for bulk production unfortunately.

Hi all

I have been a star wars fan for a long time, i got into laserdiscs a few years ago. Been watching this, i got the Definitive collection from Japan one of the last produced, with the documentaries. i got some of the best gear money can buy for laserdisc transfer. Making my own hybrid player from Sony C2Ex as base and refined overkill electronics from Mdp 999 (3 isolation transformers in one player..) 40kilos plus. Direct Bnc-Bnc (Almost lossless Belden 7731a) Runco Vfc 4404 (Commercial grade 20k$) Then s-video into capture card. I watched Goldeneye the other day, compared the output from this with my 2,5k Denon La3500 and was blown away of how good the image was, colors, skintones etc. Will make a new thread once i start capping. I believe every bit of mods help, clean power is one big part of getting the best out of it.
