I'd be sceptical about using such a slow CPU, but have you considered
using a PVR-350 which has an onboard decoder which should not impact
your system at all and provide a crisp 720x480 picture direct to your
TV and may not require any deinterlacing (it outputs properly
Lots of RAM is not really the answer, unless other running services
are taking up a large chunk of it, but I think you might _just_ be
able to get this to run. If it works, it's not likely to be a terribly
snappy system, and database queries/updates may take some time if
disk/CPU usage is high.
If you do go this route, I'd be interested to hear how it turns out.
