[mythtv-users] Video Stutter Problems

Hello,
 
I have scoured the list and the Internet and discovered a lot of good
information ... none of which has corrected my problem.
 
I'm running on 
 
 - Dell 2.4GHz/512M ram
 - pcHDTV 3000 Card
 - nVidia GeForce FX 5200
 - using NTSC with cable -- no cable box.
 - Have Video for Linux card specified -- not the pcHDTV(wanted to get
the basics working first)
 
using the latest stable branch from SVN compiled with --enable-Xvmc.  I
have "v4l" defined in my xorg.conf file.  I also have Xvmc defined in
the setup.  I believe I have also turned off all commercial flagging.
(specifics of which settings to check might help).  The processor also
spikes when I run glxgears ... not sure if that means anything.
 
When I started the image quality was terrible.  I have been able to
significantly improve the quality but it still stutters.  I ran "top"
and both mythbackend and mythfrontend are consuming all available
resources when watching TV.
 
I feel like I'm making improvements but have run into a wall.  
 
Any thoughts?
 
Thanks,
Thomas
