View Full Version : Audio and video synchronization

12-30-2012, 02:08 PM
When i play a video from USB or Hardisk, i cannot forward or backward the video for some movie. And sometimes the audio is not synchronized with the video. This happend to me with mkv and avi type. I want to know if this is a TV problem or the mkv,avi is partialy damaged? Those videos works fine on PC. My last update is Q553- and i have PFL6636M
Any suggestion?
