Hello David,<br><br>Thanks for the reply. Yes I do have the box type set. Though it is an H21, using H20 (set in <a href="http://directv.pl">directv.pl</a>) works fine as I don't see any references to H21 in your script. <br>
When changing channels watching live tv and attempting to change channels, I see "Irrecoverable Recorder Error" on the screen after it returns to the main Frontend menu. <br>On <a href="http://www.mythtv.org/wiki/Controlling_DirecTV_Set_Top_Box_%28STB%29_via_USB_or_Serial">http://www.mythtv.org/wiki/Controlling_DirecTV_Set_Top_Box_%28STB%29_via_USB_or_Serial</a> the person mentions needing to enable hardware <br>
support in order for the script to work reliably. Though I've never felt the need to do this before, I would like to try but where do I set that?<br><br>In live tv, it's pretty consistent that I can "start" watching live tv, but when trying to change a channel, I get the error. It will give a blank screen, sometimes <br>
even look like it almost makes it, then fails. Other times it works, and even other times after watching for a period of time, say an hour, live tv will shut off and <br>return to the main screen.<br><br>The external channel change parameter I use is "/usr/local/bin/<a href="http://directv.pl">directv.pl</a> setup_channel." The script is owned and group owned by mythtv and the permissions are <br>
set to 755. I have read where some people thought the serial port permissions may have kept them from changing channels but I don't believe this is the case. The <br>permssions on that file are:<br><br>crw-rw---- 1 root dialout 188, 0 2010-02-06 15:25 /dev/ttyUSB0<br>
<br>To fix changing channels I often restart mythbackend, or unplug/replug my usb->serial plug. If that fails, I remove all cards/video sources and re-add them. As you can imagine <br>I get tired of this. But for free all this software still rocks so I'm not complaining.<br>
<br>Thanks again for writing. I'll keep on plugging on this because I know it will work. It has to be something simple that I am just not seeing.<br><br><div class="gmail_quote">On Sat, Feb 6, 2010 at 11:14 AM, David Gesswein <span dir="ltr"><<a href="mailto:djg@pdp8online.com">djg@pdp8online.com</a>></span> wrote:<br>

Since you indicate it is somewhat repeatable can you directly watch the<br>
TV output of the box during a failed channel change and see what the<br>
on screen display says is happening and if the channel does change?<br>
<br>
Are you setting a boxtype on the channel change command?<br>
