Since I hadn't heard any suggestions, and the only hint I had was one <br>posting on a web site suggesting that the poster solved a similar <br>problem by speeding up the channel change script that they had <br>(completely different than what I have), I thought I would dig in to <br>that further. <br> <br>It does look to be the case here that MythTV is timing out on LiveTV <br>because the channel change script is taking too long, as evident by the <br>numerous "ret_pid(0) child(9812) status(0x0)" lines. I "strace"d the <br>directv.pl script, and saw that it was hanging for several seconds just <br>opening up the USB serial port. Out of frustration, I rebooted the <br>backend, and channel changing and live tv started working again. <br> <br>This seems kind of a harsh solution, so I am going to dig a little <br>further to see if I can just reload the usbserial and pl2303 kernel <br>modules to return things back to normal functionality.
Unfortunately, <br>right now, since I rebooted the machine, I don't have the error <br>condition to work with, so my testing will have to wait until the <br>problem comes back. :( <br> <br>-Rich <br> <br> <br> <br>Rich West wrote: <br><font color="#660066">> I searched around on Google and on the mailing list archives, but I <br>> wasn't able to come up with a viable answer. :( <br>> <br>> I've had MythTV up for a little over a year now, and, although there <br>> have been some bumps in the road, it's been running as a great solution <br>> for us. Recently, though, I was told of some problems when attempting <br>> to "Watch TV". Specifically, my in-laws were over, and it took them a <br>> couple of times to get it to display video. I didn't think much of it <br>> since it eventually worked and since we never really use "Watch TV" <br>> anyhow.. :) <br>> <br>> However, I discovered today when my in-laws
were over that we couldn't <br>> "Watch TV" at all. It would pause with a blank screen for about 3 to 5 <br>> seconds or so, then come back to the main menu screen. Recordings work, <br>> and if I go to the program guide and record a current running show, it <br>> will record and it can be watched. I tried it with and without "Avoid <br>> conflicts with LiveTV" to no avail. <br>> <br>> The mythtv logs show: <br>> 2008-01-20 23:59:59.022 MainServer::HandleAnnounce Playback <br>> 2008-01-20 23:59:59.025 adding: mythtv4 as a client (events: 0) <br>> 2008-01-20 23:59:59.028 TVRec(5): Changing from None to WatchingLiveTV <br>> 2008-01-20 23:59:59.031 TVRec(5): HW Tuner: 5->5 <br>> 2008-01-21 00:00:00.097 ret_pid(0) child(9812) status(0x0) <br>> 2008-01-21 00:00:01.102 ret_pid(0) child(9812) status(0x0) <br>> 2008-01-21 00:00:02.111 ret_pid(0) child(9812) status(0x0) <br>> 2008-01-21 00:00:03.115
