I'm not a Mythtv expert, but I have been a user since 2005.  I also hate playing devil's advocate.  So, I'm just hoping I can help you get this back up and functioning as quickly as possible.

I'm not sure that Mythtv is ready for QT5.  I know the requirements have been changed to QT48, but I haven't read anything about QT5.

Even better, I just updated my CentOS 64-bit BE/FE combo on Friday from 6.3 to 6.5, QT48, and from Mythtv 0.26 to 0.27.  Had to post-install libdvdcss and libdvdread, and it's MOSTLY working perfectly (one video out of many won't play on the FE, but plays on another FE).

Therefore, my recommendation is to remove all QT, install QT48, and compile against that.  It should get you functioning in short(er) order.

Good luck!

Mike
