Few updates.
I tested capturing in huffyuv and it workes ok now and saves a lot of space.
I upped the contrast and saturation in my capture card settings and I have to say it looks much better now. The black of space is, well, black and the colors are better.
I also noticed rainbowing (which is a bit more visible with higher saturation I think). I'm not sure what and if I can do anything about it (except for a few avisynth filters that I don't want to use). I don't know, maybe it's on the LDs itself.
I tried 2 different voltage convertors. They turned out to be chinese crap. fffffff is going to send me a quality convertor from the States.
I'll buy a BNC cable and BNC to RCA plug to reduce haloing.
Darth Mallwalker, I guess the back of your player looks like this?
Tomorrow I'm going to France for 10 days and I won't be here during that time.
