I have an HD PVR 1212 which refuses to work. I tried the following<br>
<br>
$cat /dev/video0 >file.ts<br>
<br>
however i get an error message suggesting that the video signal is not<br>
present (dmesg pasted below). To check this i connected a component<br>
cable from the 'Out' port of HD PVR to the TV and sure enough there is a<br>
video signal present which the TV showed.<br>
<br>
I am stumped why HD PVR refuses to record even though it happily does<br>
the video loopback?<br>
<br>
$dmesg<br>

I don't know if it still true, but when the HD PVR first came out *both* the video and audio had to be hooked up and properly selected for it to work.<br><br></div><div>John<br> <br></div></div></div>
