I've had my 622 for about 3 or 4 years now. I never noticed this before but we had a hurricane which pretty much destroyed our house and I put my 722 and 622 in storage for a while til the house was repaired. The 622 is in my room hooked up to a HD TV and hooked up to a SD TV in my sons room. I know it down converts the HD channels on his output but they still show up in the guide and he can watch the channel even though it says HD. Now if he turns on his TV and starts watching before i turn on mine in my room I cant get HD channels but if I turn off his TV and turn mine on I get the HD channels and his are blacked out. This creates all kinda havoc when I'm trying to record HD content in my room because its a hassle to check and make sure hes not on his TV. I am assuming this is not right and was wondering if the 622 is defective or not.
