Sync'ing a laserdisc track perfectly with the BD video was a pain in the... you know what! (^^,)
But it's rewarding! DVD should be easier, though... I have never had a problem; when the DVD has missing frames - not many, let's say 2 or 3 - at reel changes, I simply add "null" frames with audio, and the soundtrack will stay in sync!
Still, nobody wrote anything about the test color grading I did... a simple "I hate it", or "I love it"... or also a "leave it alone" will be appreciated! (^^,)
