MythTV is often compiled with no support for MMX or anything more than pentium pro optimization. If you didn't enable processor specific optimization and mmx, and opengl when doing a ./configure then this could have the bad effect. I haven't noticed much if any CPU change between .17 and .18 (Granted I run out of CVS) so I'd check that first.
