ont he back of the 622 the out put for tv2 (u can prob do it to TV 1 output as well) is labelled distribution system (or something to that effect) you can use splitter to sent the signal from there to all the TVs you want and watch your recorded/live stuff. If you have a UHF PRO Remote for TV1 you can actually change TV1 channels as well. you will have 2 separate TV channels where you can select what TV tuber you want to change the CHannel for e.g if you wanna watch something live and something is recrding on TV2 you can go to the TV 1 corresponding channel and be able to watch TV 1 output and change channels from the TV 2 location. sowy if its confusing.
