The AVI container is broken when it comes to VBR audio, you might get
alot better results by just remuxing into MKV, MP4, TS, basically any
modern container format.

You're log doesnt contain the version of mythtv you are using.
If you are on 0.25-master, there have been some changes lately to the
ringbuffer for low bitrate streams.
