[mythtv-users] Re: freeze problems

[John Goulah]

After a weekend of internet searching I realized that I should turn off ACPI 
(i think it is) in the BIOS. Now the freezing problems have stopped and I am 
at least getting the audio from my line input working with alsa while mythtv 
plays tv smoothly (finally).

If anyone knows why this BIOS tweak was necessary I'd be interested...

Thanks
John
