I've been reading up about building my own cables for my home theater set-up and I have noticed that there is some coaxial cable marketed for "digital transmission" and "analog transmission" but when I looked at the specs for the digital coax, it says it's also capable of transmitting analog signals as well--this was confirmed when I plugged my digital coax audio cable (for routing SP/DIF digital audio from my DVD player to receiver) into my VIDEO out from my DVD player into the tv, and it worked fine. So would it benefit me to simply buy the "digitally rated" coax cable for my digital transmissions and analog transmissions (Y Pb Pr, composite video, analog stereo etc)?...Will "analog" coax still carry digital signals? Someone please clear this up for me.
