Hi, As with most people my tivo has never been the same since the update that slowed them down with extra graphics and features. Still sluggish but now a little better in places.
More recently its black screening me alot. To the point the tv turns off. I can bring up menus and recordings play (which seems to fix the problem for live tv) press red buttons display for relevant channels and the info guide aswell but once these disappear its black still and then the tv turns off as there is no activity.
Have already tried other cables and checked connections. But never had a problem with tivo before the update.
