Update: mplayer works fine with older files recorded with MythTV.
However if I now do 'cat /dev/cxm0 > test.mpg' I get a nice file and
according to mplayer output it has both video and audio frames, but I
can't hear no sound. Output:

Try appending the scale filter to your filter list,

I really don't know how to debug this.
I've used pvr250-setchannel -d 0 -t and pvr250-setchannel -d 0 147.25
prior to my testing with mplayer.
I have used both plain gmplayer, and gmaplayer -cache 8192, it doesn't
make a difference.
