Checked out the shot of the stormtroopers in the Tantive, the image I have (which is a direct grab from loading the VOB into VirtualDubMod) looks to have the same overblown whites as the image on Zion's site. Can you check your original to see if this is correct?

All of the detail on the central trooper's helmet is lost. Look at the white level in photoshop:

It doesn't matter what display you use for playback, there is no way to recover detail that has been lost in the capture process.

3:2 on laserdisc question

This is what Laserman posted in another thread; you may find it useful:
3:2 Pulldown. This is where it gets frankly amazing. You all know that for NTSC they do the perverse 3:2 pulldown, wherin you use a film frame for the first 3 fields, then grab the next frame and use it for 2 fields, and then start again. (Grabbing the next frame is referred to as 'pulling it down' hence the 3:2 pulldown name. They used to just repeat the 4th frame which gives the awful juddering you can see on some early telecines.
Now to do this on Laserdisc, they player has to know which two adjacent fields actually make up the frame (othewise you might get one field from one frame of film, and the other field from a diferent frame - not good). So how does an analogue system cope with this? Easy, encode the required information in the VBI (the vertical blank interval). When making the disc, you store the info in the VBI, its often referred to as a 'white flag'. When you hit the pause button on a CAV disc, it reads the flag, and the laser assembly actually does a one track reversal (i.e. 2 fields) and can then redisplay the current frame. It is set in the VBI area outside of picture info, or CC info (its at line 11 or 274 depending on the field). If you get it wrong, the pause feature will have a 'jiggling' frame for 40% of the frames! You can see this on some discs. Sometimes just the 'picture number' is used instead, which is also encoded into the VIL.

Care to elaborate on what exactly you are working on? As I see it, the best mainstream PAL player was the 2950 (not miles ahead of the D925, but has reported better build quality, less noise and a less-tortuous signal path). This is the player I would like to get for my next version.

However, perhaps some of the smaller "videophile" companies manufactured high-spec PAL-compatible players. A thread over on avforums.com mentions the Theta players and the Voyager if it supports PAL laserdiscs looks like the kind of thing that could get somewhere close to X0 quality. Am I getting warm?

To get rid of the noise in the starfield, you can pretty much do it just by setting your black point to a portion of the video noise. Here is your same PAL shot from your capture with a different black point set.
That's a great tip and excellent looking shot thanks LM. The brightness on my TV was probably set this way, because the noise did not look anywhere near as bad when watching on the TV.

The transfer on the French discs is framed differently to the DC version, there is quite a lot of Tatooine missing off the bottom of the screen. Also the colours are not as saturated.

I think the main thing to note is that although there seem to be more stars in my PAL version, there is also a load more chroma noise (some of the black space is blue-ish). And that shot from the X0 is the raw cap before any processing, whereas mine is from the finished DVD (both jpgs have been resized to the correct AR).

Easynews is what my brother uses, and he's quite happy there. I think Easynews has a web interface that you can use to make downloads easier, but I've never really looked into it.

I've heard good things about shemes.com Usenet service (the maker of the free binary newsreader "Grabit"). Not only do you get Usenet access, but you also get access to an automatic newsgroup indexing service which means that you can search all the newsgroups without having to rely on "human" indexing services like newzbin.com.

Seriously, I don't know exactly what I've spent -- and I don't want to know, so I don't have a figure to give my wife -- but it's a lot.

Just to redress the balance - I wouldn't want the idea that you need to spend a lot of cash putting people off starting their own projects - I spent in total less that £150. That's for player, discs and capture card.

I'll probably re-sell the player - but if I do, it'd only be to buy a 2950!

I think you're right. There's really no such thing as PAL or NTSC on a DVD, since that refers to analogue colour coding. But due to the PAL/NTSC legacy, you do need to worry about the number of lines and the field rate. PAL-M has 525 lines (~480 on screen) at 59.94 Hz, which is the same as NTSC. An NTSC DVD will have the correct resolution and framerate, the output electronics on the DVD player should do the rest.

This is something that Zion and I have discussed previously - in the end he kept the official screenshots as unscaled, whereas I added an option to my "unofficial" comparison page to select resized or raw view. Personally I think that the scaled versions allow a more direct comparison; when you're comparing a laserdisc rip the detail is won or lost in the capture process, and any detail lost in scaling screenshots is negligible.

There are no fades on the French discs.
The first change is the bad one, between the shot of Ben and Luke lifting the damaged Threepio and the borked image of Ben's hut.
The second is between the scenes "we've captured a freighter..." and the Death Star docking bay.
The third is between the shot of the Millenium Falcon escaping and "Are they away?"

BTW Citizen, how are you doing with the audio sync issue? Are you finding you have to trim small sections of the audio from the DC discs in order to maintain lip-sync?
