[mythtv] Recording while watching LiveTV problem

[tarek Lubani]

A followup on the bug report..

1) Here is a screen shot: http://tarek.2y.net/myth/snapshot.png .. As an 
aside here, I don't know what the mythepg is doing in the back.. I don't 
see it.. It may be something to do with the snapshot program?

2) This screen is starting to go away now.. At least in this round of me 
playing around.. It comes up about 30 seconds before a recording is set to 
begin, and right now disappears when the recording begins, setting the 
channel to the correct place and starting the proper recording.. If I find 
out more on when it hangs (this is the first time it *hasn't* hung), I'll 
let you know..

3) This error seems to occur whether I'm in 800x600 or 640x480.

4) I reproduce the error with the following steps:

 a) start mythfrontend
 b) watch live TV
 c) hit "m", then pick a program to record on a DIFFERENT channel in the 
next half hour
 d) go to a console, and set the date to 40 seconds before the recording 
should start

Then that screen pops up.. I cannot get a backtrace, as when I try to 
debug, it says the following and doesn't let mythfrontend start:
