>I have set up a Myth frontend on a reasonably decent Dell Inspiron D830
laptop (1920x1200) which also feeds my HDTV in the bedroom.

>It has an nVidia Quadro NVS 140M video card with 256M RAM (which is
apparently the minimum video memory necessary).  The processor is a 2.6GHz
dual-core Intel Centrino chip, with 4GB of main memory.  The machine is
using wired Ethernet to talk to the network, not wireless.

>I'm running Ubuntu 9.10 64-bit with JYA's latest 0.22-fixes binaries,
using the 190.xx nVidia drivers.

>However, none of the VDPAU playback profiles work - period.  Slow, choppy
(basically unwatchable) video and audio, even with only 720p files, with a
lot of prebuffering pauses in the logs (but no other obvious errors) - it
seems that it's not even using VDPAU at all.

>CPU+ is better but still noticeably choppy, and after about 10-15 minutes
starts bogging down and I have to kill playback.  Normal and Slim aren't
really any better.

>However, from all I've heard, VDPAU should work with this setup.

>I can't figure out what I'm doing wrong here...any help would be appreciated.

>Thanks.  For what it's worth, my combined FE/BE downstairs (beefier CPU,
same OS and version of Myth) is running an 8600GT with VDPAU without any
hiccups.

Did you move this forwards?  

I suspect you need the 512M RAM video card version as the BIOS will not allow borrowing of motherboard RAM.
