I have had this happen on my trunk build of mythtv [20568], built it last
night.  The caps on my old NVidia 6200LE gave up the ghost recently, I was
using ffmpeg which worked very well.  Now that I purchased a 8400GS, I
wanted to check out the VDPAU.  I'm having lots of problems with it.

1) Every once in a while when I execute mythfrontend, it brings up the
theme background then crashes back to the desktop with just a "segfault"
error.  It'll crash like that twice in a row, then work.  This may not be
VDPAU since I haven't even initiated video playback at this point, but it's
really weird and it did not do this with my 6200LE.
2) I have a studder problem when the OSD is up, lots of others have had this
issue.  Apparently, it's a problem with any overlays because turning on the
closed captioning also makes the video unwatchable.  I wonder if this is a
limitation of VDPAU, or is it something that might actually work someday.  I
ask because we use closed captioning a lot.  If it'll never be as good as
ffmpeg, I'll just toss this new 8400GS and get something else that can do
it.
3) Occasionally, selecting a recording will cause the frontend to crash
reporting seemly random errors (different error description every time).
