I would be feeding this signal into a broadcast grade infinite window TBC. The question I have is about the video level and the non-standard sync some have mentioned. The video level before the TBC is 0.8V p-p instead of the standard 1.0V p-p and I'm not sure what the sync is like. Is the video signal at that point even usable? Yea, TBC is Jitter control to keep a stable looking picture, example tape cassette has wow and flutter except the bwey good decks. Ao basically the ld picture is going to show wow and flutter mayne not bad though.

Publius mentioned in this thread how someone was tapping the digital composite signal from the TBC in an LD player. This was after TBC rather than before like you are asking, so I'm not sure if that helps. He does provide a link to the thread from another forum where the user is trying to do this. Maybe that will help you if he explains how he does this?
