I've been having issues converting some of my videos, specifically .mkv files with Vorbis audio. When converting with two passes, it stops about halfway through the second pass stating that there are too many audio packets in the buffer. Some work arounds I've come up with either involves dumuxing the .mkv file, converting each stream seperately (audio with Audacity and video with N800 Video Convert), and remuxing the streams or converting the file with AVIdemux. The problem with the former is that it takes too many steps and too much time while the problem with the latter is that it takes more time to convert and the conversions don't always wind up being optimal for my N800 and I have to run it through N800 Video Convert.

Is there a reason that this converter doesn't play well with Vorbis audio well and can it be fixed?
