Crestron programming

I am trying to have a DVD added to the bus and have it programmed to play on any TV via the Crestron system.

What's a reasonable way to estimate how much time that should take? I mean, I can program my remote control from scratch to control several different systems in under an hour using a web based program. Changing a single device would take me less than 10 minutes. Is the Crestron that much more complicated?

Yes it is that much more complicated,I had a HD receiver installed and I think that it took 3 hours or so.

That helps. They said 6. Maybe to discourage me.
