Can someone confirm this? If so, the wiki should be updated.

The following is a chunk of the code starting from about line 2030 in 
mythtv configure.

NONE of the subsidiary switches are tested if xvmc is not set:  the else 
clause just forces xvmc-vld to 'no' if xvmc is 'no'.
Not only should the wiki be updated but the 'help' code at the top of 
configure should note for the xvmc-vld and xvmc-pro lines that xvmc is 
required.
