Hello...Sorry, first post here and looking for some help. Hopefully someone will be patient enough with me...As I have no idea what I'm doing! Alright, here's my situation... I currently own: Samsung 32" LCD HD TV YAMAHA HTR-5920 HTIB Rogers Digital Cable Receiver (soon to be a HD PVR Box) Toshiba SD-4990 up converting DVD player Xbox 360 PS2 3DO Currently...I have everything hooked up to my Samsung TV and an optical cable going from the TV to my Yamaha receiver. I don't think this is hooked up correctly because I am unable to use DTS with my PS2, Xbox 360, DVD player or TV. Now, I'm aware that I need to have each device connected through my receiver...Although, I only have one optical and one coax input on my receiver... I do have a connection switch, which allows up to 4 component, composite, S-Video connects with optical audio outputs. I would assume that I will need to have an optical cable for each device running to that switch and then another going from the switch to the receiver? That's a lot of cables! Also, I can't decide whether or not to connect all of my devices directly to my TV or to my receiver? Once I get that switch setup I will be able to connect all of my gaming systems to the switch, and then to my receiver and then use my Samsung TV as an output monitor...Would that be the best way to setup? Finally, My DVD player is connected via an HDMI cable directly to my TV. My receiver doesn't have an HDMI input...So, is it even possible for me to get digital surround sound from my DVD Player?? I'm sorry...There are so many questions here and I hope I explained myself well enough. Please, if anyone can offer any suggestions it would be greatly appreciated! Thanks! Oh, also...Very stupid question I'm sure...However, my Digital cable box only has a coax digital audio output. However, the only spot on my receiver for a coax output is under the DVD input...So, I would need to run the cable through the DVD output on my receiver...Is there any way to connect a coax to an optical input? Or, would it even matter??
