I’ve been able to find a workaround, but this is really odd.
I have to go to Audio/Video stettings > A/V Devices and select Appl FireWire and uncheck the “mirror on the desktop” box.
The video and audio then play fine through FireWire. So I have the playback end worked out but this is going to be a pain in the butt for editing. The system I’m on is about 6 months old:
G5 2ghz Dual Processor
2.5 gb Ram
FCPHD version 4.5
It’s not a hard drive issue, since I isolated all the drives trying to figure this out. It’s not a question of glitchy source material, it happens with DVC Pro videotape digitized today or last month; and VHS source material produces the same problem. I have 2 different FireWire devices to acquire from (not ever connected at the same time). It’s a totally new problem altogehter, the odd part is why all of a sudden??
