So I have to run a somewhat long cable between my audio rack and my projector. My question is would it be better to run a long DVI cable to the projector, move the media center PC to the projector and run a long optical cable, or run both cables the same length? I wasn't sure which would allow for the audio an video to stay in synch or if it really mattered. The distance is going to be between 25 an 50 feet. Probably closer to 50 once I route it along the walls to hide the cable. I figured video would lag faster than the audio but I didn't know if that distance would really make a difference. Thanks for the help.
