I don't think it would work with video signal, but if something like this exists for video signal, then it could work!
Why not? Composite video is just an FM signal.

Audio range is within 1-20KHz (up to 100/200KHz sometimes) while composite video is up to 3.58MHz (NTSC)... so, I don't think that device could handle signal in the orders of MHz... but I'd happy to be proved wrong!
What about my idea about RGB capture?

An RGB capture would rely even more on the '90s video processing of the LD player than using S-Video output does (further down the chain of decoding from composite color encoding). So I'm skeptical. We want to go in the opposite direction.
I agree, but you know, I prefer to test and see results (bad or good) with my own eyes... at least, it's only a (one more) test!

Agreed.

I'm aware that the laserdisc signal is composite, and RGB output is a "constructed" signal, but I'm open to any solution... sometimes, old technology is better than newer, who knows!
Still looking for "the perfect comb filter", in particular for PAL signal; a Snell&Wilcox TBS-185 could be a very good candidate, but I've found some of them only in US, and shipping price could be almost more than the device price itself... (**n)
...and still waiting to know further info about the phase-inversion trick; if it will work, it will be possible to obtain a dot-crawl free image with just a good capture card (with a bad comb filter too) and two capture stages.

I owe Blackmagic Intensity Shuttle for Thunderbolt. I am sure that the chip/hardware is the same as that on Pro and Extreme.
The problem is that Blackmagic Intensity Shuttle for Thunderbolt drops (or should I say skips) the frames at random without informing the end user. If it doesn't report dropped (skipped) frames, how would anyone know that the frames dropped? Of course there's no way.
But because I am doing simultaneous capture from my LD player to BM via Composite in to DMR-ES25 (Component out to BM) and the 2nd capture to VC500 via S-Video out, I can compare the end results. Out of 5 such simultaneous captures for an hour video, one time everything matched, 3 times BM lost 4 frames and 1 time BM lost 2 frames.
After that I also captured using ATI 750 HD PCIe. The end result matched with VC500.
In addition while BM gives very descent quality using Component inputs, the capture using S-Video plain sucks. For a product that costs roughly $230 vs VC500 $25 or something - this is unacceptable.
metaleonid: Are you capturing to an SSD? What does the Blackmagic Disk Speed Test say?
Using an SSD (or a nice RAID setup) is more-or-less a requirement when capturing with any of the Blackmagic capture devices.
In Blackmagic Media Express with the Blackmagic Intensity Pro, at least, there's a setting to stop the capture if any frames are dropped. You can also set it to output black frames in place of dropped ones.
Also, FWIW, the s-video input on the Blackmagic Intensity Pro looks just as good as the component input. I can't tell the difference.

Hi,
I have 15" MacBookPro with 500Gb SSD. I did test capture with HD 1080i as well as 720p. My HD can handle it. I also have the setting to stop capture if dropped frame is detected.
I will however try to set it to insert a blank frame.
But my question to you is, are you certain that your BM doesn't drop the frame? If I weren't doing simultaneous capture, I wouldn't be able to find this out. I suggest you do the capture with BM and either at the same time or after that do the same with "proven technology" (i.e. VirtualDub). See if you got skipped frame.
As for S-Video, I tried both DVP 649 DVD player and LD-S2 Pioneer Elite LaserDisc player. I didn't like the results at all. Diamond VC500 gave much better results.
Another thing is that Intensity Shuttle might indeed be different from Pro or Extreme.
--Leonid
When I unchecked stop capture if dropped frames are detected, that was even worse. Now I lost 8 frames in one hour of video. I plan on returning the device and get the extreme version instead.
My problem: I have only one PCI-E slot, and is occupied by the video card; I have other free PCI slots, but there are many good capture cards that are only PCI-E... Maybe I found a solution:
don't take in account the upper card; the important one is the lower... this was tested into a PC, same model of mine, and worked flawlessy.
Now, my question: is the ATI 750 the same height of the upper model? Looking at many pictures online, it seems so, but I'd like to receive an answer from an actual owner.
Also, if other capture cards will fit, I could consider on of them too.

I will have to probably take it back regarding Blackmagic Intensity Shuttle. Most likely it was Panasonic DMR-ES25 that wouldn't process all the frames and would skip frames randomly. I used Panasonic DMR-ES25 as a middleman between my LD player's composite output and Blackmagic Intensity shuttle device. Recently I put Panasonic DMR-ES25 in between my VCR and LifeView FlyVideo 3000FM capture card and noticed a few skipped frames.
I will dig further and report what I will have found.
It looks like DIAMOND released a new driver for the DIAMOND ATI Theater 750 PCIE (TVW750PCIE) on 2013-09-10.
Get it at the following hyperlink under "Support & Downloads": http://www.diamondmm.com/tvw750pcie-diamond-pcie-hd-tv-tuner-card.html
Please tell us if it fixes the AGC issue!

I've found that the Luma Ramp pattern on DVE interacts with the ATI 750 USB's AGC, but it isn't immediately visible to the naked eye the way that some problematic non-DVD sources apparently are. With the help of a scope filter, this test may be useful as an easily-distributable check. That said, it doesn't trigger a really bad capture device I have that's triggered by a lot of other DVD content, so it certainly isn't foolproof.
Test results with ATI 750 USB:

drngr: Did you use the new driver I mentioned in an earlier post?
JEDIT: Nevermind. I just realized that you're using the USB one. Do you have the PCIE one too?

Great news: just won an auction of the Sweespot capture card!
When I will receive it - hoping it will work, as the seller stated that "it should work" - I'll test it immediately and post a brief review; don't hold your breath, because it will be here in not less than two or three weeks...
I'm pretty happy as it is the first one I found on the bay in about a year, 'cause I didn't want to spend 149£ + VAT for a ten years old product... even if it's an old capture card, it should do pretty well its job, plus it could be used in conjuction with Dscaler to improve and upscale analog video signals like laserdisc - it exist a special custom version of the software to work with it!

What would be a recommended relatively cheap PCI-E capture card that would be best for capturing VHS?
Finally the Sweetspot is my hands... long story short, it went from UK mainland (seller) to Northern Ireland (a friend of mine) who "forget" it for two weeks, then he remembered suddenly (after I called him) and then sent it to me in Italy...
It's in pristine condition, in its original OEM box, with manual but nothing more... Now I should download driver and DScaler dedicated version; but, as I'm uploading AVP:R right now, and don't want to "disturb" my poor PC, I'll set up everything in the next few days; then, I'll post - again - with a brief review.

First impressions of the Sweetspot.
After installation, the driver didn't work and PC freezed... then, after removing the old PCI catpure card everything was OK.
I used first DScaler (tailored specifically for this card); quality is really high; it could be used as a real-time video processor, with nice filters; the only critic is that it's not possible to record video at full heigth...
Then I used VirtualDub; here quality seems lower, maybe because it must be properly set, where DScaler is preset to works perfectly. A strange thing is that I must capture in RGB24, as no other color space is supported...
I'll report more info when I'll finish to discover its secrets!
