Well, I had a lot of problems getting my cheap Athlon-1800XP to work
(on-board video problems, on-board sound problems) so I decided to go out
and get a real machine :) A Pentium4 2.4GHz with 512MB of fast RAM and an
NVidia GeForce4 MX-440.

Installation was a snap (after I got the correct NVidia drivers), however,
I'm getting jittery video even at 320x240. My Athlon-1800XP was able to
do 640x480 without ANY problems.

I've seen a couple posts in the archives about this (and everyone seems to
be using NVidia cards...can this be the problem?) I haven't found any
answers thought. Here's my info:


- What codec are you using?
Tried rtjpeg and mpeg4...rtjpeg actually performed WORSE!

- Are you using the nvidia binary driver?
No. I'm using the nvidia module

- Is your mysql colocated on the server with mythtv?
Yes.

- What is your disk speed? 7200? 5400? Other?
7200 RPM

- What is your disk buffer size? 2MB? Other?
[ cat /proc/ide/hda/cache ]
2MB

- What are your dma, multcount, and prefetch settings?
[ hdparm /dev/hda ]
