Tried that and got mythtv to link, but as soon as I selected "Watch TV"
it crashed with the following backtrace:
#0 0x908311ec in objc_msgSend ()
#1 0x96547a0c in numberForKey ()
#2 0x96546bcc in CGDisplayCurrentMode ()
#3 0xc91c2008 in VideoOutputQuartz::Init(int, int, float, int, int,
int, int, int, int) ()
#4 0xc903f070 in NuppelVideoPlayer::InitVideo() ()
#5 0xc904b884 in NuppelVideoPlayer::StartPlaying() ()
#6 0xc90ca830 in SpawnDecode(void*) ()
#7 0x90024910 in _pthread_body ()
Maybe I'm on the wrong track but my guess is that
CGDisplayCurrentMode() was calling a QuickTime function whose name got
mangled because of the namespace.
I can look into this if you like (now that I know that this isn't just
a setup problem on my end). I'll see if I can split videoout_quartz
into two files, and have different #includes in each. If I can get it
to link that way and still get a crash, then we can add a namespace and
start looking elsewhere for the cause of the crash :-)
