The comparison screenshots:
The laserdisc shots posted are approx. 712x275.
Most laserdisc captures have 4 vertical lines of black on the left and right (hence about 712 not 720).
It's also important to note laserdiscs are analog and have no true width. 720 is just a convention since it's what DVDs commonly use.
LD signals contain an analog strength of up to 5mhz. This translates to only about as much data as 528-544 pixels in width. That's one reason why LD to DVD conversions look softer and are easily compressed on to single layer DVDs.
Horizontally there are only about 270 lines of movie data on a laserdisc (after cropping the borders). This is an estimate since laserdiscs technically only have about 400-425 lines NOT 480. That is true lines of resolution, the difference is extrapolated in software (further softening the picture).
So the X0 shots are the real captures as they are (as post on the X0 site anyway), preserving all picture information in the capture, yet of slightly higher resolution than the source laserdisc.
The DVD captures on the other hand are anamorphic and have a TRUE height of 360 horizontal lines (cropping the black borders). If OCP were to post 720x360 it would be distorted. If he were to match the height of a laserdisc shot he'd be throwing out picture data that really exists. So you would resize the width to produce equivalent aspect ratioed screenshots. This is no more artificial at 849 pixels than the laserdiscs using 720 (which again has no more than about 544 pixels worth of information).
As for the odd half sized screenies, they are only there for comparison: the full frames aren't available since OCP is obviously using what little is posted on the X0 site.

Frankly if I were running the X0 project I'd go dark until September, saving time and money.
If the '06 DVD are really and truly completely borked then start up again, anything else is just plain crazy.
