Steve are you transcoding?  It seems to cause a "Unknown codec", or it 
can cause another error, "NVR::AudioInit() This Unix doesn't support 
device files for audio access. Skipping".  In gentoo, you need to use 
the +oss flag to make it work right.  Even though you have +alsa and 
would expect alsas compat layer to work.
