Just to compare I put debug=1 in quite a few of the dvb modules and 
tuned to a few channels.  It's now really hot here and the card appears 
to only tune to one channel and then crash when tuning to the next one.  
The setup is that I have xawtv open watching the dvb input (ie not using 
an analogue feedback to a bttv card), then I tune using tzap -r 
"somechannel"

I tuned to BBC ONE, then ITV 1 and it crashed twice now tuning to ITV1.  
According to the logs, it appears to have crashed slightly earlier the 
first time, and I am posting full logs below of the second crash (sorry 
they are so verbose, wasn't sure it was appropriate to trim.

Another thing to note, when a lockup occurs for me, tzap reports a 
"signal" of 3535.  Not sure if this is an additional heuristic that you 
could make use of?
