[mythtv-users] First stab at mythtv...

[Michael Janer]

My P4 1.8ghz system can record MPEG4 at full 720X480 with no problems.
 
Take a look here http://www.mythtv.org/docs/mythtv-HOWTO-3.html#ss3.1
 
In short, your EPIA board has been compared to having the processing power of a PII 400-500 MHZ box.  This is why it can't do encoding and decoding at the same time.

Then you're doing something wrong... at what bitrate were you trying to
record, and is DMA enabled on the disk you're recording to?  I can do
480x480 at 2200bps MPEG-4 with my 1600+.
