Currently I have my computer connected to the TV and receiver to watch DVDs. For the audio I'm using a 1/8" stereo to RCA stereo cable connected from the sound card's digital audio output to the receiver's CD digital audio input. For the video, I connected the S video cable from the video card's S video-out to the TV's S video-input. I was wondering if I get a stand alone DVD player will the sound and video performance be improved? I think it would because shouldn't using audio cable such as optical or coax improve sound quality over 1/8" stereo to RCA stereo cable? I'd also imagine that the video output would be improved as well because isn't the DVD output quality better than using the video card's output? With that said, please let me know if it's worth purchasing a stand alone DVD player. Thanks.
