Comment (by mo.ucina@…):

 I have upgraded my installation to rev v0.24-238-g2a9d9f5 . My operating
 system is Fedora 14 - 32 bit , using latest updates . After upgrading I
 rebooted the pc , then using LiveTv tuned into a channel . Almost
 immediately the problem started where video would slow down in bursts the
 speed back up to normal speed every 10 to 20 seconds , while during these
 slowdown periods audio would loop and last few words would be repeated a
 couple of times over , while audio is repeating video would go on and the
 two would go out of sync , then audio and video would re-sync and play
 back normally for another 10 to 20 seconds .

 My normal playback settings are using "VDPAU High Quality" profile . I
 changed the profile to "High Quality" which uses full software decoding
 only , and the problem went away and the playback is perfect . However my
 CPU loading increased dramatically . I tried to set the playback profile
 to "VDPAU Normal" , but as soon as I did this problem  started immediately
 . So at the moment I still have rev 270 installed and running with no
 VDPAU , playback is perfect , but CPU is running hard .

 I am using Axel's latest Nvidia Drivers 260.19.44 with my GTX-450 card  ,
 using the HDMI output for both audio and video .

 Any suggestions on how to proceed further greatly appreciated .
