I have tried using software for my pda's and a radio shack 8 in 1 kameleon and neither can do most of the features for this reciever. Namely I can't switch to many of the inputs, can't change analog/digital input, and most important of all I can't change surround modes. I lost the remote to this so I can't learn the commands. Anybody here know what to do? (would calling to have the remote updated help?)
