Mark - here's where the 700 shines. It has 20 devices available. Just use one of your empty devices and setup your DLP TV. You can continue to use the remote for your existing TV until the new one is delivered. Upon delivery, you are ready to go with the DLP (you will need to tweak any existing macros set up for the older TV for the new DLP).

Once your equipment is all hooked up, you can delete the entire device for the old TV and move the new DLP device around to where you want it.
