Yeah I agree, It's not worth it without getting a HD signal it seems...and what's holding me back is the need to run everything thru Tivo wich only allows S-Vid. So unless I forget about Tivo or bipass it and only record in SD but watch in HD OR upgrade to their HD DVR I will probably just wait and see what my options are in a few months.
I don't think it's worth it to get HD service yet if i can only get a few channels in HD anyway regardless of tivo or not.
