Patches applied cleanly and compiled. Is there a particular reason
--disable-audio-oss was removed from configure? It also seems that
MPEG2VIDEO_XVMC codec did not build. I received a message about could not
open codec MPEG2VIDEO_XVMC followed by a seg fault when trying to watch a
1080 ATSC recording.
Let me know what additional testing or info I can provide to you.
