Okay, I'm not disputing the fact that video is stored on laserdiscs as composite video.
I'm aware of the basic signal flow inside of a typical laserdisc player. The fact remains that the x0,x9, and r7g will pretty much always produce the best real world results when capturing via the s-video input as long as you have the comb filter settings right when capturing.
I'm not sure that you understood that when I say that the rf signal is captured from a test point using Happycube's method that this means you are intercepting the signal after it has left the pickup but before it hits any analog filters much less the digital tbc/comb.
If you come up with some good results please feel to share them here with us. I know there was a guy on another forum that had posted the exact same method you describe of tapping the digital tbc output on a player and running it into a sdi converter then to a pc.
He never posted any results though and that kind of soldering is typically beyond the average joe such as myself so that kind of mod will probably not be attempted by me unless it turns out to be the absolute best possible way of capturing a laserdisc lol.
On another note: Rotj-1478-85 is gout-synced. I just need to figure out how to crop the subtitles and include them in the black bars of the final encode. I've been working a lot lately or this would have already been done. Hopefully by next week it'll be on usenet.
