WDTV: Video files with AAC audio out of sync

I just loaded the firmware update and now mp4/m4v movies with AAC audio are several seconds out of sync. 

Did you ever get any help on this?  Since there’s been no replies, maybe you should try contacting WD’s Technical Support about this. You can do so either by phone or email.
