 I upgraded from Fedora 18 (nv driver) to 19 (nouveau driver, as 19 got rid
 of nv), and all myth viewing started having double-speed video, but the
 audio was still 100% ok (normal speed).  18 to 19 did not change the myth
 versions.

 I tried every myth option, every decoder, every deinterlacer, and it
 stayed double speed.  Even setting audio to NULL didn't help.  Did it on
 live TV as well as recordings.

 When I did an while-watching options->playback->playbackdata it would show
 the mpg was 29.97 fps and the playback FPS was 59.75 to 59.99!!

 Testing with
 mythavtest -O LocalHostName=abcdefg
 /data/Mythtv/Recordings/1888_20130708085900.mpg
 made no difference.  It still played double-speed.

 Testing with mplayer /data/Mythtv/Recordings/1888_20130708085900.mpg
 and the video was fine (not double-speed).  Problem is in myth only.

 I switch to the binary nvidia driver and the video was fine (not double-
 speed) without any other changes.  So the problem appears to be unique to
 the nouveau driver.

 The output from myth while double-speed shows nothing out of the ordinary.
