EPG screen doesn't work and breaks LiveTV

[anonymous]

SVN 11835

When I press 's' in LiveTV, so EPG screen appears. This is also the case when I press 'm' and choose EPG in the menu.

When I press ESC, the screen goes black and no frontend menu appears. I have to restart the frontend.

Here are the last lines from the frontend log:

2006-11-28 22:09:52.108 TV: StopStuff?() -- end 2006-11-28 22:09:52.108 TV: Changing from WatchingLiveTV to None 2006-11-28 22:09:52.184 DPMS Reactivated.

I can confirm the bug. This wasn't happening in svn version 11831. This is the behaviour of mythtv I have seen:

I start mythbackend, run mythfrontend and go to Watch tv. EPG (EIT) guide appears as usual. I choose a channel to watch. While watching LiveTV I press 's': No guide appears. I press 'm' and choose program guide in the menu: No guide appears. I press 'Esc': I get a completely black screen. I had to kill mythfrontend by Ctrl-Alt-Esc.

I restart mythfrontend, go to watch tv. LiveTV appears when the program Guide should have appeared. Press 's': I get no guide. Press 'm' and choose program guide: I get no guide. I kill (Ctrl-Alt-Esc) mythfrontend.

I restart mythbackend and start mythfrontend. I go to Watch TV: Program guide appears. I choose a channel to watch tv. Press 's' and Guide doesn't appear. 'm' and choose program guide in the menu: Guide doesn't appear. Press Esc: black screen. I Ctrl-Alt-Esc kill mythfrontend.

This is the whole console output of the third run (the last paragraph):

I think the problem lies in the line that says "Unable to launch application". I hope this helped. If you need further info, just ask for it. Best regards.

I am not sure if it occurs in 11831. I just checked out fresh 11830, compiled and I still see this problem. One can still see the EPG from the recording scheduler

[anonymous]

The revision that I used before was 11787. This revision had aworking EPG screen.

[anonymous]

Still happens at revision 12156 with a clean compilation.

Update from last post on this topic: I've deleted all the files mythtv, mythplugins and myththemes install, and reinstalled all again again. The bug is still there.

[ryan.buschert@…]

I was having this problem too after upgrading to SVN 12156. The attached patch seems to fix it for me. It looks to me like the problem came in with changeset 11828 with the "nvp->IsNearEnd?" check on line 4971 of tv_play.cpp. With 12156 as is, if I pause LiveTV for a few seconds, then unpause, the program guide shows up fine.
