KiwiNZ:The last update that was to make things quicker etc has resulted in sound and picture stutter after channel change that I have not been able to resolve. I don't want to to tempt fate and get my box replaced and end up with a complete lemon.

I thought I was going mad - this is happening to me too, recorded and live!  Screen pauses but the sound continues, then the video runs fast to catch up with the sound!

Perhaps I should log a call also...
