Just to provide a bit more information, I'm using debian-multimedia, which is why my ffmpeg libraries are newer than what's in the standard debian repositories. This thread on Audacity forums ( http://forum.audacityteam.org/viewtopic.php?f=18&t=28048) documents the problem, and also includes a patch. According to that thread, the change appeared in ffmpeg 0.5.1. If I'm reading the version numbers correctly, both debian-multimedia and experimental have ffmpeg 0.6 (with slightly newer version in debian-multimedia), and the standard squeeze install has 0.5.1. (which also means that the standard squeeze libraries might experience the same problem)
I would prefer not to try to install a different version of the libraries since I don't have any experience working with different repositories like that, especially since I would have to deal with the dependencies. (I'm mainly worried about getting everything back together again when I'm done...) If somebody could try it on a standard testing and/or experimental install that would be great.
