If you experience an out of sync issue - where the sound does not match the video, make sure your Language & Time Zone are set correctly. This seemed to fix the issue for many Avov owners especially the Teal Top boxes that have no update yet.
Ch 203 is still bad out of sync with audio/video. Ch 205 server is out of time and causes 15 to 30 second repeats, or skipping up to 30 second to catch up. You are losing me, AVOV. There are alternatives!
