As an update, the syslog had an error amongst the thousands of saa7146 error
messages there was an interrupt error suggesting to use irq polling in the
kernel, after a quick tweak of grub it is now keeping the cards loaded (so
the kids didn't kill me for failing to record Dr Who!).

 

We're still pixelating, but the patch needs a kernel rebuild so I'll need to
fit in some time between work and recording schedules.
