I'd advise you to delete those two broken codecs. Then uninstall and re-install AV-DVD-Player-Morpher. Latest version here:

Then reboot and see if that helped. I confess I don't see the benefit of having that, but best not to screw around too much with your setup.
Normally, most folks don't need too much more than an MPEG2 codec, XviD, maybe Real Alternative and Quicktime Alternative, and a few others. All formats can be played with Media Player Classic or Videolan. Even simpler would be to have only ffdShow and MPC/VLC. The more codecs one has, the more potential for conflicts. It can get to the point where it's easier to do a format/re-install.
Nevertheless, it can be difficult to pin down problems like that. Your computer may have other problems as well, of course. Anyway, see if that helps. Good luck.
