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></div></div>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>

<br></blockquote></div></div></div>Hi Mark,<br><br>Normally the command "v4l2-ctl --device=/dev/video0 --set-input=2" will just set temporarily the input and will not override the mythbackend setup.<br>During the various test I made, I noticed the HDPVR is touchy with the cables. I faced sometimes the /dev/video0 being changed to /dev/video1, simply because I unplugged the usb cable (I'm using ubuntu).<br>
What I would check:<br>- on the HDPVR, only having composite cable being plugged, if for instance you have spdif in but not out, it may not work<br>- on the backend, cross-check again the card is well set on /dev/video0 <br>
- backend input card, making sure you have your source setup on Composite (3r line normally). I guess your problem is here.<br>- still backend input card, composite, making sure you have /bin/true in the "external channel change"<br>
<br>Finally if all is good, please provide the log error.<br><br><br>

<br></blockquote></div></div><div><br>I finally figured out why its changing to component and not using the composite. On the "Input Connections" page, I had set up the component input with the video source and not the composite one. Once I removed the video source from the component and added it into the composite, it stopped giving me the above problem. I'm still not getting any video when I go to watch live tv though. And my channel changing script works when I call it on the command line, but it doesn't work through the live tv page. I noticed that when I use the cat command the HDPVR lights up blue, but when I try to watch through the live tv page it doesn't. Anyone have any suggestions. Also, where is the error log files located?<br>
