I don't think I have ever see a receiver in Any price range or brand with a DVI port.
Ask your cable campany for a Cable card with HDMI or is does your tv only have DVI?? For you computer, does your TV have a DVI port for PC??? then you can run audio outs from your computer to the receiver or a PC surround sound system.
DVI on tv's has been out dated about 4 years now. A few brand tv's will have HDMI for tv usage & DVI for PC usage, DVI ports on tv's has mostly been fazed out about 2-3 years ago & replaced with HDMI.
I need to replace my Sony home theater. My question is my PC and cable box connect via DVI. Is this a problem? I am ready to spend $1,000 for the right receiver but I am somewhat a neophite.
