I searched around on Google and on the mailing list archives, but I
wasn't able to come up with a viable answer. :(
I've had MythTV up for a little over a year now, and, although there
have been some bumps in the road, it's been running as a great solution
for us. Recently, though, I was told of some problems when attempting
to "Watch TV". Specifically, my in-laws were over, and it took them a
couple of times to get it to display video. I didn't think much of it
since it eventually worked and since we never really use "Watch TV"
anyhow.. :)
However, I discovered today when my in-laws were over that we couldn't
"Watch TV" at all. It would pause with a blank screen for about 3 to 5
seconds or so, then come back to the main menu screen. Recordings work,
and if I go to the program guide and record a current running show, it
will record and it can be watched. I tried it with and without "Avoid
conflicts with LiveTV" to no avail.

I've seen some references to the possibility that the channel changing
script might be just too slow (using directv.pl), but I don't quite know
how to speed that one up. In fact, it seems slower than I remember. I
did some quick timings, and it is taking ~10 seconds for the
change_channel script to exit. Could this be the source of the
problem? Is there a way to tell mythtv to wait, say, 15 seconds, before
giving up? Is this a case where mythtv *is* giving up, or am I barking
up the wrong tree?
