Hello,

I'm having a problem with some HD channels, e.g. Fox NFL on Sundays, 
which display video but there is no sound. Attached is the mythtv output 
when trying to play back a file recorded yesterday. If you want to 
download the clip you can get it at

    ftp://sapodilla.rsmas.miami.edu/pub/angel/chan7.ts

That file is about 100 megs but you can download the first 10 megs:

    ftp://sapodilla.rsmas.miami.edu/pub/angel/chan7-small.ts

This file was recorded with an Air2PC card if that matters any.

Angel
