[mythtv-users] Freezing video problem

[Jenks, Mark]

I'm not even sure what to search on for this issue.
 
Asus m3n78 PRO motherboard w/ 4gb of ram, and 2 1TB drives.
 
I have a WinTV-HVR-1800.  If I try and watch HD using mplayer
dvb://channel, I get errors, and it skips real bad. "Too many video
packets in the buffer"
 
If I try to tune in w/ Myth, I can see the first 5-10 seconds, and then
the video freezes, and it just hang there,  I can ESC out of it to stop
it It doesn't do this on non-HD channels..
 
But if I open a ssh to the box, I can see the .mpg file growing at a
normal rate.   If I stop myth, and use mplayer to view the .mpg, it's
fine.  I can even copy it to another box and watch it there w/ mplayer.
So, it's recording just fine.  Just not playing liveTV.
 
I have tried every Nvidia driver that I can load on it, and the problem
stays.
 
glxgears runs at 2000 at the normal screen size.  If I make it half
screen or bigger, it goes down to 450.  Video issue?  It's not a HD
issue, iostat 5 2 shows everything is fine, and it does actually record
it.
 
What am I missing?  Where should I look next?
 
I am trying to watch it on my 17" CRT, and want to take it to my
flatscreen w/ HDMI in the end, but if it doesn't work here, I doubt it
will work there.
 
Thanks!
