Comment 7 for bug 104613

I think that problem could and should easily be handled by a further
divertion of nvidia-glx and nvidia-glx-new.

Simply divert users of /usr/lib/libXvMC.so.1 to
/usr/lib/libXvMCNVIDIA_dynamic.so.1 and the problem is solved.
No need for error prone modifications of config files.
