Hi
I am currently working with a analogue>digital copy of a VHS video tape. This is an .avi of 740 megs (0.74 Giga bytes) and has a duration of 47 minutes. This loads and plays with no problems in VP 4.58.
Is it the size of your .avi that is causing the problem?
Try loading the avi and then clearing the cache of unused files and then see what happens.
Any chance of trying a 20 minute .avi with a smaller size and seeing if that plays to the end?
Nat
