Video Lag Issues

Video Lag Issues

A friend with whom I'm working on a 2 hour video project is having issues with Video lag which we can't seem to figure out.

My system is 1st Gen Powermac G5 dual processor PPC 2ghz w/4gb RAM and 2 internal 500gb hard drives running OS 10.4.8 and ProTools LE 7.1 with Quicktime 7.1

His system is a new Mac Pro Dual Intel Quad-Core 3.0ghz w/4gb RAM and 2 internal 500gb hard drives running OS 10.4.8 and ProTools LE 7.3.1 w/Quicktime 7.2

The video is a 7+gb file and we're doing some ADR loops. On my machine (3+ years old) everything works smoothly, on his machine he's experiencing major lag on the video when the video reaches the beginning of the loop, the audio continues but it's as if the picture itself is having a hard time keeping up. We're a little baffled by this as his machine should by all means run circles around my machine.

Anyone have any ideas as to what might be the problem?

All suggestions are welcome!

I don't think LE is coded for Multi-processor Multi-core machines. Check with
