Anyone else have minor audio sync issues with their X2? Sync starts off perfect but after a few minutes can be up to 1 second off. If I change the channel and switch right back it will be perfect again for a few minutes. Same if I pause and unpause with the green key on the remote.
It happens on most channels/birds; however, some channels work perfect and they are mostly in HD.

I've had a few email exchanges with tech support but I think there is a major language barrier.

This video shows the video lagging slightly behind the audio.
