Hi there, many people have had problems with skipping sound and freezing picture and I'm no different! I've only had Sky installed (Amstrad PVR3) 2 months ago and sound has skipped/frozen already! Would replacing/upgrading the HD fix the problem or is it the actual box or signal? I'm reluctant at this time to call Sky and get a refurb box although I will at some point fit a 250GB drive - I didn't want to do it yet! Thanks.
