Pro Tools Video Sync Offset

What determines the video sync offset in pro tools? Is it the device you're sending video out to or the speed of your computer etc?

The reason i ask is that we're trying to get all our computers at work running the same. We have 6 mac work stations all using a Canopus ADVC110 To send video out to tv sets (we all have different tv's if that matters) but we are running different computers, we have 3 Mac pros and 3 G5s. Should we all be running the same sync offset or is it specific to each computer? Is there a way to figure out exactly the 1/4 frame offset we need or do you just kinda do what looks right.

also 2 of the workstations (for the composers) use logic, not pro tools, so i'm sure its done differently for them.

For Pro Tools:

Depends on the device & the speed of your computer.

Sync up a hard sound effect IN PT.... switch to video out firewire and then nudge it by quarter frames until it syncs back up.

Enter than number into the video sync offset for quicktime.

Probably will be around 4 frames (16 quarter frames).
