[mythtv] Updated patch for directshow filters with MythTV (for CoreAVC)

Mon Feb 26 00:03:40 UTC 2007

I am not running latest SVN version but rather gentoo 0.20_p12825. I have
started getting segmentation errors on the backend when editing recording
(possibly also other circumstances). Frontend != backend in my setup. Please
pardon me if this error has been fixed.

Has anybody tried tried running the {front,back}end compiled with Purify to
identify possible leaks?
