Hi,
I have a front projector L300U. Generally you have a choice of putting the DVD player close to the projector with short video cable and long audio to the speakers & receiver (which are usually on the front of the room under/beside the screen), OR have the DVD player close to the receiver & speakers with short audio cables and long video cables over to the projector. Since I want to use a DVI video connection I placed my DVD player under the projector, because long DVI cables are very expensive, and can have problems. This allows a single digital coax (SPDIF) audio cable to the receiver from the DVD player, and then I have short speaker cables. If you don't plan to use DVI, long component cables are good and reasonably priced, but the way I saw it was I could pay for 1 long audio digital coax, or for 3 long video component cables, and I prefer a short DVI. The audio sounds great. I bought Blue Jeans cables and they sound great.
