I thought I might have had the same problem until I tried it on a new PC!

I think I might have made some progress myself now using kernel 2.6.1 
with the built in drivers and increasing the latency timer for the card 
to 128 (from 32). I have managed to record several shows without any 
crashes or lockups.  I find it worrying that changing the PCI latency 
can stop the kernel from crashing, sounds a bit dodgy to me.  Anyway, 
I'll leave the box running and recording a few more shows and see if it 
really is more stable than before.

The latency timer change might fix the problem under 2.4.22 with DVB 
1.0.1 but I didn't try that because I've discovered 2.4.22 doesn't 
support the agp controller on my new motherboard! :-/
