Try Settings -> Video -> Playback -> Advanced Playback Settings. Make 
sure AVSync2 is checked then set ANSync2 -> audio correction. The 
default value is 10. This should  fix lip sync within a short time after 
a skip. A higher value will resync lips quicker but could cause jitter 
at other times. A low value will take longer to resync but may improve 
smoothness of playback in general. However is all cases the sync should 
come back eventually.

Another possibility - check Settings -> Video -> Playback -> General 
Playback -> Enable Music Choice. Disable this unless you are watching 
music choice channels. In some cases having this enabled could cause 
loss of synchronization.
