Hi,<br>
I followed the instructions found at <a href="http://www.mythtv.org/wiki/HDPVR" target="_blank">http://www.mythtv.org/wiki/HDPVR</a><br>
and everything goes well until I get to the part where you run the<br>
command "cat /dev/video1 > test.ts". I get the error message "cat:<br>
write error: Bad address". I'm not exactly sure why and I have been<br>
trying to figure it out for the past 2 days. I also can't view live tv,<br>
it shows up as a black screen. Any suggestions?<br>

Are you sure your device is on /dev/video1 instead of /dev/video0 which is usually the default? Do an ls /dev and see which /dev/videoXX you have, then follow the wiki based on that.<br>

</blockquote></div><br><br>My device is on /dev/video0 for sure. Using Roberts suggestion I ran "v4l2-ctl --device=/dev/video0 --set-input=2" to set the video input to be composite. Now I can use the cat command to create a video file that actually works. I have a new problem though. When I open the mythtv front end, the video input is set to 0 which is component. I think that's why I'm getting a black screen when I try to watch live tv from the front end. I have the back end capture card setup to use the composite inputs but that doesn't seem to work. Also I now know that my channel change script doesn't work. Why would the front end switch the video input on me?<br>
