I have some ac3's recorded here that contain multiple bitrates. It starts at 448Kbit, then switches to 192Kbit, then back to 448Kbit, and so on. When I try to cut it with VDubMod, or any tool for that matter, it sends things completely out of sync. After hacking together a program to verify there was indeed the bitrate changes I started thinking about why this might cause a problem. The most reasonable assumption I could come up with is that VDubMod incorrectly assumes all ac3 frames will have the same framesize so when it switchs bitrate it is not cutting the frames properly. Before I started hacking up some more code to see if this really was the problem, I figured someone on here might know just how VDubMod handles cutting ac3's ... whether or not I'm completely offbase in my theory.
I apologize if this should be in the development forum instead of the Vdub forum, but as it's a question more about VDubMod than actual development I thought this the more appropriate forum.
