We just had Dishnetwork set up recently. I also previously had TIVO. I have a DVR receiver for 2 TV's, and just a receiver for 2 more TV's. Can I hook TIVO to either of them or only the receiver where I am not using a DVR. If so, would appreciate a little tech no how in "how to do so." If it can't be done, can it be hooked to a TV without anyhook to Dishnetwork - and how would I do that? I still have stuff taped on TIVO and want to access it. TIVO is great - so userfriendly, not like my new Dish DVR.Thank you for any assistance you can offer. Gabby648
