Which wouldn't have this as it was backed out shortly thereafter
due to problems related to the previous check in. Bob and XVMC

Log Message:
Fix chroma ghost in OSD (ie, pause box still kinda showing up in the upper right of the exit options menu).
DTK's patches for capturecard setup enhancements (add distinct pchdtv and ivtv screens) and bobdeint.
Me: Fix the bobdeint patch, as it turned XvMC into a onefield deint.  Fix flickery OSD display with xvmc + bob.  Make the paused video display a full frame for higher quality stills with bob.
