Indeed.  I find that when it gets into that mode, a cold restart will
"fix" it momentarily.  F1 on Speed is tough to listen to in tinny
audio.

Interesting.  I am running Mythbuntu 8.04 with the LTS updates:

$ uname -a
Linux vidbox 2.6.24-23-generic #1 SMP Wed Apr 1 21:47:28 UTC 2009 i686 GNU/Linux

What script are you using?  I am using directv.pl snagged off the 'Net
last summer.
