Description
When watching an HDTV program with XvMC enabled, whenever the OSD is displayed, the playback becomes jerky (sound and video). When the OSD disappears, the playback resumes are normal, sometimes. Other times, playback stops completely until I hit ESC and return to the program, which fixes playback for a few minutes.
I've found that forcing ChromaKey OSD fixes the problem. I've followed the guide in the HOWTO for enabling ChromaKey, however an error message occurs at runtime (output will be attached). The error message was being produced by code designed to keep the ChromaKey OSD from running on Nvidia 6/7 series cards, however, mine is an FX5500. Changing the if statement to if (0) at videoout_xv.cpp:1257 allows ChromaKey to be used, and playback to proceed normally.
I'm running mythtv-0.19 on an amd64, X.org server 7.0, and an NVidia FX5500 graphics card.

It should be noted that I /always/ get the VideoOutputXv error message, and video seems to work fine regardless.
