Recording from a DVB-T card like this is a doddle for the CPU.  There's 
no work to do, except, basically, to put the received data stream in a 
file. LiveTV is hardest for it to handle, as it has to record and 
playback at the same time (it all gets recorded to the ringbuffer before 
being displayed).

I am far from an expert, but I was led to believe that a 1GHz cpu would 
be sufficient.  I am using a 2.2GHz Sempron though (with 512MB ram).  
First guess though, could it be your graphics card, and/or it's 

I have an old TNT2 card in mine at the moment, and it works OK, on 
standard definition (720x576), but can't quite handle the higher 
definitions.  That's OK for me, as I think SD looks good enough.  It's 
DVD quality anyway!
