I have a 'freeze" problem on my newly installed H21. Installed last thursday -11/8. Seamed to run fine for a while. (I many also have the dormant lockup problem but my wife runs it 20 hours/day so it really is never dormant). The freeze up happens when I hit the backup (six second button) and sometime when I hit the 30 second forward button. The picture freezes, as in pause, but play button has no effect. Neither does any of the other play/rewind buttons. However, the guide will come up, the playlist works and an item in the playlist will select and play. After a while, 1 minute or more, the freeze goes away and the program resumes. I've only seen this on "live" shows, but I have no hit the six second rewind button on recorded shows. HAs anyone else seen this or do I have a bad disk/box?
