(Mac PowerPC flat-panel G4, OS X 10.3.9)

New to LimeWire: Please Help!

I successfully (I think) downloaded a TV program for viewing. It's on the downloads list as "Complete". It is an AVI file.

When I try to play the file, Quicktime Player activates and "acts" like it's playing the file (the timer is counting off the seconds, etc.) , but all I get is a blank white screen and no audio!!

Suggestions??? Many Thanks!
