oy, that blows.
if you haven't upgraded your box in a while, i might try to get a NEW model box (i highlight that because unless you ask very firmly, they'll often try to give you and old one) to see if it works better with the new config.
one thing i've learned, though, is to NEVER turn a box that is working fine (as your box was before their "upgrade", anyway) until you're sure that the new box works well. whenever i do that, i hold on to the old box and just pay the pro-rated monthly fee when i finally do turn it in. that's after turning in a fine hd box and going through three s****y new ones trying to find one that worked and not having hd cable for a couple of weeks.
good luck. glad mapman got his 1080i working (on my comcast boxes there's a little button on the front that lets you scroll between 480, 720, and 1080i and then just uses your last choice as the default output).
