Check out the upper-right corner of the picture, the Denon has three in and 1 out:

Now that you're question has been answered, let me encourage you to ignore the answer.
There is a large home theater faction which believes you should not run your video through your receiver. Analog video degrades if you look at it funny. Cable length, connectors, size, build quality, A->D, D->A, interferance, etc. By running the cables through the receiver you multiply those problems by the added cables and the upconvert process (A->A, upconvert, D->A, or, worse, a totally analog upconvert.) The faction believes that you should run your cables directly from the source to the destination (DVD->Tv, VCR->Tv, PS2->Tv.) This way you get the best possible image from your source displayed on your Tv. In addition, either your source (which has the best possible knowledge about the data making up the source material) or your destination (the Tv, which has the best possible knowledge about how to display the material) should do the upconvert, not some funky device in the middle. Most remotes can do macros, or get something like a USB-programmable remote (like the Harmony 659, ~$110 online) that can switch the audio receiver and display at the same time.
But if you want to switch video then the Denon is probabally a good choice.
Oh, you should also be aware that the new trend in receivers if digital amplification instead of analog amplification. Smaller receivers with more power, less heat and less distortion. I'm not sure Denon makes one yet, but Panasonic and H&K (DPR 1001, ~$450 on amazon) do. The H&K only has 2 Component in and 1 out, but it has SIX digital audio inputs in and three out.
