Are you planning on running the video from the various sources directly to the projector, or through the PDSD? You need to think about how you are going to switch the video projector between the various sources you might want to use. The projector can be used as the switching device but only if you have the same or fewer sources for that type of input. Another reason to buy a new-model projector is that they typically offer more source inputs that can be controlled by the projector. Typically, a projector will have one composite video input, one set of the three component video Pb Pr and Py inputs, perhaps an S video input, and a single HDMI input. But some of the newest projectors have two HDMI inputs. Now count your possible video sources and what type of video input to the projector might be required for the best possible video from each
.
If you have HDTV cable or Sat, that will probably go into the projector through an HDMI input. Analog (SD) cable will take a composite input. Standard or Blu Ray DVD can go in through a component or HDMI input. Standard DVD can go through the S video input. (My experience has been that a DVD running under composite video is markedly inferior to component video, but I can't tell any difference between component and S video on standard definition 480p DVDs). Output from a VCR is generally just a composite video signal. In my case I run component video direct from the DVD player to the projector, but since there is only a single composite video input on my projector, I pass the composite video from the VCR through the 6.1 Pioneer receiver as well as the composite video from my standard definition cable, and use the Pioneer as the switching device. At some point I will add high definition cable and that will enter the projector directly through the available HDMI input. However, if you plan to run Blu Ray AND high definition cable, a projector that has two HDMI inputs or an audio unit that inputs and allows switching between 2 or more HDMI sources would be a neat way of controlling everything. The problem with twin HDMI inputs on the projector is that you have to run an extra separate HDMI cable from the source to it...perhaps a problem in a ceiling mount where one would like to simplify the wiring into the projector as much as possible, and long HDMI cables are not cheap.
So think about your various video sources, how each type will enter the projector, and from what point in the chain will you control each.
It would be helpful to draw this all out in a diagram.
