[mythtv-users] Via CLE266 (via-slice) HW acceleration problems (segfault)

I'm using the onboard video out an rca jack to a tv.  I don't think its
accelerated properly, as my mythmusic visualizations skip.  It looks
great for tv though and NEVER skips.  I am using also audio.  One hang
up here is to make sure you configure myth to use alsa.  Its something
like ALSA:0,1,0 or somethign like that.  I'm not in front of my myth
machine right now to tell you the exact line but you can probably find
it in the archives somewhere.

I never could get tv out stable on the 350..thats why I'm using the
onboard.  Quality on the 350 might have been slightly better but the
stability with the onboard far outweighs the loss of quality.  Good
luck.  Let me know I can help.
