 I changed the profile names for Default, High Quality, Low Quality and
 Live TV to something else. Then when a recording starts, the mythbackend
 segfaults.

 I traced the mythbackend with gdb:

 Program received signal SIGSEGV, Segmentation fault.
 [Switching to Thread 32771 (LWP 22067)]
 0xb7daee99 in NuppelVideoRecorder::SetOptionsFromProfile (this=0xb5db0008,
     profile=0xbf3ff774, videodev=@0x811db34, audiodev=@0x811db3c,
     vbidev=@0x811db38) at NuppelVideoRecorder.cpp:334
 334         QString setting = profile->byName("videocodec")->getValue();

 I see in the code that it uses hardcoded names like "Default" and "Live
 TV". I don't have any experience with the mythtv code, so I don't know if
 this is intentional or just bad coding.

 Anyway, I changed the names back to the originals, and now the it does not
 segfault anymore.

 Since the frontend allows for profile name changing, it should not
 segfault.

 BTW: It did not start to segfault until I rebooted the computer.
 Everything worked after the namechange before I rebooted...but after the
 segfaults started coming.
