[PLUG-AV] dvgrab insanity

[Leon Wright]

Euan,

I had discounted a solution like that at first, due to the fact you could
bump a cable causing a bus reset we may not catch. However the syslog
monitor to cater for that and doing an existence check on the guid file,
this should catch when someones kicked a cable out.

# cat /dev/mem | strings | grep -i cats
Damn, my RAM is full of cats... MEOW!!
