My biggest concern would be how the broadcasters are going to handle it? Locally (Balt/DC area), analog is almost never out. Digital on the other hand, goes blank, has audio issues (wrong audio feeds, not Dolby Digtial, audio dropouts), wrong PSIP info, wrong clock info & guide info embedded in the signal. Plus signals that don't always have the correct channel mappings (32-1 is sometimes 33-1).
There's a big thread about DC OTA on AVS, and several local tech people that work for the stations post on there. It's not all that uncommon for them to say something like our XXX device hung, and needed to be rebooted, that's why XXX problem was happening.
Hopefully digital TV will be more stable next year, but I doubt it as the stations have already purchased their equipment and are not likely to upgrade again.
