Yeah, they are mostly lossless AVI's (huffyuv codec). The chd tool can convert them to CHDs. We worked pretty closely with Aaron Giles while he was highly motivated to work on the laserdisc stuff.
But like I said, while it is nice to have these, it would be nicer to have raw ADC captures of the voltage coming out of of the back of the laserdisc player (or even better, the voltage level from the disc itself but one thing at a time).
