Advertisements Since the last software up rev I can't find a format on my HR20 that will unsqueeze 16:9 on the new HD channels when displaying on a 4:3 TV (I have it connected to both sets). It worked fine last week. A reboot provided no help. Software download up revs are typically a good thing, but a double-edged sword, and no one knows that better than the Tivo 6.x team. No one seems invulnerable to the demons that could be set loose. This time DTV screwed the pooch. Not a good sign.
