I am in Chicago Il, Central Time. I received the update today, 9/15 @2:28 AM

I just received my D* HR22-100. From time to time, the audio is out of sync with the picture. It can be on the local channels or the nationals. It can be from very slightly out to almost 1/2 of a second off. Is there any way to correct this? I used to see this on my previous box, a D* Tivo SD...
