Hi...<br>
<br>
I'm running mythtv 21 and can not get XVMC to work.<br>
<br>
If I run the "slim" profile, I can watch live NTSC, ATSC 720p, and ATSC<br>
1080i. But the 1080i stutters (pauses about 1/4 a second for ever<br>
second). So I am trying to invoke hardware decoding on a Nvidia 6000<br>
card. But, I am sure I am doing something wrong as trying to watch a<br>
live 1080i pegs the processor w/the mythfrontend taking about 92% of the<br>
processing power. BTW, the screen goes black and I have to kill the<br>
front end through a telnet session. To envoke XVNC I switched to the<br>
"cpu--" profile.<br>
<br>
As I have not been able to find an example of a mythfrontend log where<br>
XVMC was properly launched, I can only guess at what is going on. Below<br>
I cut and pasted my mythfrontend log during the start up of a 1080i live<br>
TV session. Can anyone see a problem (yes, I see the sound problem, but<br>
this configuration was working while using the "slim" profile.)<br>
<br>

...that's it, now the CPU is running the mythfrontend about 92% of the<br>
time. The other 8% are split between the X server and the mythbackend.<br>
<br>
...thanks for any help<br>
