Don't automatically assume that it's that one card that has gone kaput. My 
original setup of three K-World DVB-T cards ran well for ages and then I started 
getting errors. I assumed like you did that one of the cards was about to go, so 
pulled each one to try and isolate the problem, but although one looked more 
iffy that the others I wasn't entirely convinced.

That was about the time multi-rec appeared, I didn't actually need the third 
card any longer, so left it out. My gut feeling is that either there was some 
problem with the PCI bus - or a particular slot - or the power supply struggled 
with three cards in the motherboard (those cards get /real/ warm).

Try swapping stuff about. You may find a duff PCI slot or that your PSU is 
borderline. The card you pulled may work perfectly well in a different slave 
back end.
