This is on a Windows 7 Home Premium 64-bit machine with HDMI to a AC3 capable 
receiver.

LAV by itself does no such things.
It can be one of these things:

1) Language preferences
2) Your player overrides the track choice.

Usually its the 2nd.

They are both English.

I think I have the fallback setup wrong.  I will double check in subler.

Looks like LAV will choose the AAC stream over the AC3 stream if they are both 
2 channel, even if the AC3 is a higher bitrate.

However, as long as the AC3 stream is 5.1 it will pick it over the AAC stream.

Higher bitrate does not always mean better quality. AAC has better compression 
ratio than AC3.

Thats why bitrate is not a factor in the decision. Its lossless > lossy codecs, 
more channels > less channels, and thats all.
