gnutv does look very close what I want, it gives a wide range of options 
for setting up TS recording and enabling the output of an onboard mpeg 
decoder which is perfect. Unfortunately I need TS recording and video 
output from the the onboard decoder at the same time, which it doesn't 
seem to do.
I've looked through the source code for gnutv but can't find where it 
sets the device up for hardware decoding. If I could find it I would be 
able to set it up an additional option to do both, but I can't find 
where it does device control.
