I have just tested this with current cvs and get the following problems:

Live TV doesn't work at all with or without xvmc:

At this point I sometimes get a SIGSEGV in mythfrontend or else sometimes
it returns with an error message to the menu.

Watching recorded video does work, but if I try and do anything interactive
(fast forward, change volume etc) the OSD comes up briefly, then mythfrontend dies with a SIGSEGV. This is quite repeatable. The log is not very interesting in this case. It shows a few "Prebuffer timeout" messages then dies.

This is all with SD DVB-T. I'll back out the patch and see if any of this is
due to something else.
