As I use ATI cards every day (and so use neither XvMC nor have access
to HDTV) the only messages in the log that I could see which *may* be
causing you problems are the above ones relating to video sync - what
you you have got configured for vsync in mythfrontend? What other
specific video playback settings (different playback modes etc) have
you configured in the frontend? Are you sure your NVidia is
completely/correctly installed? Have you started over with a fresh
xorg.conf file?

To other NVidia users - are these messages normal for a correctly
configured NVidia card?
