Please delete the Makefile after applying the patch and make again.  
There shouldn't be a Makefile in the patch (but is) and it prevents a 
new (correct) one from being built from the .pro file.
I recommend building all apps, as dependency checking doesn't happen 
until the myth* apps are built (ven though the only thing you need to 
install in this case is libmythtv)
Once you get that far, please send me the debug logs after enabling 
'--verbose playback' if you are still getting segfaults.  Debugging 
directshow issues is difficult due to the binary-only filters.
