I just got my 990 yesterday after waiting for several months to get things together (money) and setting it up now looks very daunting to me. I am working alot so this whole process may take 2 or 3 weeks since I'm limited on how much time I can spend doing this. My first decision seems to be whether I should run everything through the 990 or not, are the majority of owners doing this?

The way I have things hooked up now to different inputs is (1) Direct Tivo, (2) VCR, (3) Front input don't use, (4) Dvd, (5) Zenith HDTV OTA tuner, (6) Ant.2 ,OTA antenna (the signal being split to go to both HDTV tuner and Ant.2). I can't figure out if I can still do this if I ran everything through the 990 or not but what I like to do is to be recording on both Tivo tuners (besides watching one of them) and use the previous channel button on my remote to jump back and forth between one of the Tivo tuners and either my HDTV tuner or Ant 2 to check on ballgames. Could you still do this? I use a MX-500 with macros to jump from one input to another also. I just can't envision how this will work with everything going through the 990 after years of simply switching inputs. Is what I doing now actually easier and more functional plus the advantage of running the satellite directly into the tv.

After someone answers my first question, where do I start in trying to setup the 990 even though it may sound dumb to ask this?
