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.
