This failure may be an indication of a more generic dual audio stream problem that has cropped up in RC2 (and perhaps RC1). I can no longer playback files derived from terrestrial Freeview HDTV programs. These files contain dual format sound tracks (AAC and AC3 I think). In my case they are recorded by a MythTV backend. XBMC Dharma RC2 chokes, freezes solid on Linux and displays black screen under Windows 7, OSD still comes up but pressing the soft stop button doesn't do anything. All other channels (single format audio tracks) all playback fine. When I ran Beta4 I'm pretty sure TV3 playback worked OK. I have tried this on two Ubuntu 10.04 systems and a Windows 7 system, all with RC2. Anyone else seeing this? Perhaps I've missed the bug report and this is already known about.

I have a log I can post but thought I'd put the question out there quickly first to see if anyone else is experiencing the issue.

A log + backtrace on linux would be useful.

OK, I'll see if I can generate a full debug level log. Not sure about the backtrace generation yet. In the mean time a few lines that look relevant from the log file I do have may mean something to someone who know what they're looking at:

I'm not sure what is going on but I tried it again last night, with debug logging enabled and it worked (different TV3 recording). I then turned debug logging off and tried it again and it still worked! Given that 4 different XBMC RC2 installations (2 Linux and 2 Windows) had previously failed on the 2 TV3 recordings I tried them on I can only conclude at this stage that there was something else about those particular recordings (not the dual format audio stream) that XBMC didn't like. The recording had played back in Windows Media Player OK though. I'll look into it further. In the meantime if anyone else experiences similar issues I'd be keen to know.

Yep, I just tried again with one of the original TV3 recordings. It would appear more related to some kind of 'corruption' in the file that XBMC can't handle, though some other media players can. I have noticed that XBMC is quite temperamental generally about video files that are a result of recording off air (DVB-T, H.264). Often it reports the length of the file incorrectly and sometimes it's impossible to skip through without XBMC bombing out and dropping back to the menu. Could be I need to upgrade my external antenna, though signal quality reports from my TV's and HDHomeRun unit seems to suggest it's pretty good (Signal Quality 89%, Symbol Quality 100%). When I get a moment I'll produce a debug log for the XBMC crash event when it tries to play one of these 'corrupt' files.
