[mythtv-users] Bad sound quality with Plextor M402U

I don't have the old post in front of me, but the problem your having is 
most likely a side effect of a bug in the myth code. The M402U only 
supports 48k sampling rates, but when you select 48k the myth encoder 
fails to assert this setting and falls through to the default of 41k. So 
you get audio that sounds like complete crap. If you search around in 
these forums and possibly on the referenced divx forum you will probably 
find the 1 line patch that fixes it. I'm pretty sure it was submitted and 
fixed in the cvs version as well.
