Dreadful problems with my quad core.
Gone back to my laptop.
Video files which play perfectly on other machines play with the A and V out of sync.
In P.P. CS4 captured files, which look ok during capture, get a strange hued tint in edit mode. Sometimes this is corrected by effects.
The edit window sometimes doesn’t display the last file I called up.
A and V go out of sync on the timeline.
I always run P.P. with no other apps. running.
Could be the A/V hardware as suggested I suppose.
Purely Audio programs work fine.
