Guys, long time d* guy, I have and old hr10 250 looking to replace. I have an old Sony directivo and old RCA Directivo, an hr 21-700, and some receivers. Total of 8 feeds coming off my multiswitch. I was told that to replace my hr10-250, I'd need to put a slim multiswitch in (I want wmrv) and then I'd have replace ALL of my receivers since they won't work with slim (except hr 21 w deca adapters). That's a complicated proposition as i have two full stereo racks, plus several other remote locations throughout the house. On the one hand, it may make me upgrade to get hidef in rooms I don't now, but still that's almost a wholesale change out. I still have a boat load of programming on my upgraded tivos. Just trying to understand what I am getting into. Anyone have a clear design or "schematic" of a recommended layout for multiple room video with my type of gear?
