Update:

I have compiled and installed the latest v4l drivers:

If, straight after doing this I run "cat /dev/video0 > /tmp/record"
cat: /dev/video0: Input/output error

If i rmmod hdpvr I need to run this command twice before it begins recording...
root at mythtv:/tmp# cat /dev/video0 > /tmp/record.avi
cat: /dev/video0: Input/output error
root at mythtv:/tmp# cat /dev/video0 > /tmp/record.avi

.... Any ideas?

I have a workaround whereby a bash script runs the following command every three seconds "v4l2-ctl --device=/dev/video0 --set-input=2 --set-audio-input=1". This will get it working around 90% of the time. I do notice that when it does actually work, the blue record light turns on once, turns off, turns on again and begins streaming.
