Audio Plays Faster Than Video

I have several video files on the WD Live Hub.  But after the last few firmware updates I have noticed a slight difference between the aadio and video speeds.  After playing some videos, I notice that the audio is playing slightly faster than the video.

Does anyone have any ideas?

I have used Handbrake (Apple TV2 preset) and converted using the MP4 Codec.  As far as I can remember the default is variable rate.

the lyp sync could be caused by diferent reasons…

try getting info for the file … test with different file types

Finding that the MKV is looking better than the MP4…any reasons why?  Does the WD Live Hub play MKV’s better?

don’t know why this is happening…

try to see if the codecs are the issue…
