I am a newbie to MythTV and Linux, so please help point me in the right direction.<br>
<div id="AOLMsgPart_2_378f36ff-0a14-4f1b-9ba5-68d678b7e2aa"><font face="Arial, Helvetica, sans-serif">
See below for my hardware/software setup.<br>
I have 3 issues I would like help with:<br>
<br>
1. I am getting errors when the backend starts (full log of backend start at the end of this post):<br>
</font><font face="Arial, Helvetica, sans-serif">2007-08-30 21:32:54.690 Channel(/dev/video1) Error: SetInputAndFormat(1, ATSC) <br>
while setting format (v4l v2)<br>
eno: Invalid argument (22)<br>
2007-08-30 21:32:54.722 Channel(/dev/video1): SetInputAndFormat(1, ATSC) <br>
Setting video mode with v4l version 1 worked</font><br>
<font face="Arial, Helvetica, sans-serif"><br>
2. My Frontend has locked up a few times. I think it is only when I tried watching the NTSC tuner while recording on the ATSC tuner and I exited watching live NTSC TV. The screen was frozen (blank or Myth frontend main menu). I had to power down and re-start. I had to run the optimize perl script to get things working again. Maybe it is just that my hardware can't handle it, but I guess I hoped it would exit gracefully and not crash. I haven't actually gotten the NTSC tuner working so that may be part of the issue. I am mostly interested in recording HD, so the NTSC tuner is lower priority. I put a log of this happening a the end of the post. <br>
I followed these instructions to install the NVidia drivers:<br>

They mention a problem with Intel integrated video (which I have), but the link (below) is dead:<br>
<a href="http://doc.gwos.org/index.php/Nvidia_Intel_Integrated" target="_blank">http://doc.gwos.org/index.php/Nvidia_Intel_Integrated</a><br>
<br>
3. I get stuttering while watching live ATSC TV or while watching recorded ATSC content. Should I be able to get smooth playback with the hardware I have?<br>
<br>
Thanks for any pointers!!<br>
