I have 5 Dtivos, each set to an alternate remote address. The only preset tivo code in the urc-200 is address "0", which will control all tivos. So i need to learn each and every command for all five tivos. See thats not the problem, with mx-600 I would need to do the same thing. The problem is, on the urc-200, each learned command needs to be taught twice, doubling the time it takes to learn all from 5 tivos.

With the urc-200 only having 5 keys per page to the 10 on the mx-600, you need to scroll more often, in every operation. It gets tiresome.

The RF response of the urc-200 is as good as the mx-600. They both communicate directly with my old pyramid RF extenders, so if you owned a pair you wouldn't need to purchase separately the MRF-100. I only paid $55 with shipping for the urc-200 off of ebay.:)
