I've had my V6 installed for a month and I am delighted with it so far. The speed and the extra tuners especially. However over the last 10 days or so I have noticed lip sync problems on both live tv and recordings. It seems fine early in the day but gets worse as the day wears on. I have tried rebooting the box which does help for a while but then it worsens. Is there anything else I can do or will a future software update address the problem.
