We just got A&E HD on our cable system and I haven’t seen a *single* thing yet in true HD.They didn’t even show A Few Good Men in HD the other night.
Direct TV has about 9 stations in HD right now, no word but I'm assumung you will have to get a new HD MPEG4 HD receiver to receive the new channels.
Right now I have the TIVO DirectTV HD box that apparently will not be compatible with the new channels, the DVR that DirectTV gives you without TIVO really sucks.
