Let's begin with apparently I know so much less then I think I know. :b About 8 months ago I started working on my HT and bought a 5740 and a Sony dvd player. At that time I purchased component cables for the video and analog cables for the audio. I then realized that I had digital optical cables on my new reciever and thought once I save up some money I am going to get one of those fancy cables. Well a couple of months went by and I was just happy to have my surround sound all working and I forgot about the digital cable. Then one day I was at BB and saw a nice optical cable and thought I should buy it so I did. The cable is really nice and it looks great laying next to my HDTV but the problem is my Sony dvd player will only except a digital coaxial cable. I swore at myself a little but decide to keep the cable because this is the begining of a hobby and I am sure I will need this cable down the road for something else. Another couple of months pass and I buy a digital coaxial cable because I know it will fit and that is when I realize that my Yamaha only excepts the coaxial in a spot marked CD. I hook the cable up to that spot and just like magic the sound comes out of my speakers. At first I am really happy because after two failed attempts and a decent chunk of change I have managed to hook up one cable. Then I realize that since my reciever is hooked up to the CD location that I seemed to have lost all the DVD options that I had before. I use to be able to choose the dynamic range I wanted and play with some other features it had but now it just says "STRAIGHT" across the front of the display. Please tell me I have not been beaten. I hate to think this one cable has knocked me off my high horse of HT dominance. Amongst my friends I am a God. I have a dvd player, a satelite, a vcr, and a stero all hooked up to the same tv. I know for many of you all this may not seem like much but in my circle this is a big deal.
