Advertisements 99% of the time the TIVO works fine using the HDMI connection, but every once in a while it completely blacks out for about 20-30 seconds. When the signal comes back on there is the briefest of flashes of a TIVO messages that says something about the HDMI cable not being "allowed." The thing I don't get is that it seems to be perfectly allowed the rest of the time so why the problem every once in a while? There's no rhyme or reason as to when it blacks out. Sometimes it doesn't happen at all for a few days and sometimes it happens more than once in an hour. I've tried different HDMI cables as well as a different port on the TV. Anybody have any suggestions (besides doing away with HDMI all together...) Thanks.
