[mythtv-users] PVR-350 Performance still BAD

Frutillar frutillar at comcast.net

I have followed Jarod's and others' documentation and I still cannot get my 
live tv to be shown at normal speed on my system.  It is VERY jumpy (one 
frame every so often) and no audio.  I see X just fine (well, the desktop is 
bigger than the screen, but I see most of the desktop); it's the live tv I am 
having trouble with.  I have an EPIA M10000, so if the pvr-350 tv-out 
encoding/decoding is not in use I definitely see it.  I definitely feel the 
pain.

I do have PVR-350 TV-Out selected in MythTV and I made sure that /dev/video16 
is specified.

Please help!!
