I have run tech for three dance performances in town that required
syncing 3 dvd sources. We've done the shows about ten or 15 times now
and we've had no problems keeping them in sync. My biggest concern
was the fact that the films needed to stop & start four separate
times. I just stacked the three players and used a single remote. The
entire show runs a bit over an hour with the longest continuous run
between stops being about 15 minutes. Worked like a charm.
I'm not saying there wasn't any drift but if it did occur it was
invisible. Probably would have shown up in the audio if we had
monitored the players simultaneously because two identical audio
sources even one frame out of sync starts to produce an echo effect.
