Comment 3 for bug 1172502

File : Hack - Triumph of The Nerds - The Rise of Accidental Empires (1996) 1of3 (PBS).avi 500 MB

If you download this file and try to convert it with WinFF and I get the following output inside terminal :

With Pitivi it is no longer crashing but hangs while Estimating time for rendering.

I'm trying to use Pitivi because I want to merge all 3 videos into one.
I believe the only way to reproduce this bug is to use a AC-3 audio codec in a video file and try to use it in Pitivi.

If you can download the file in the begining and only that one and try it out.
