I'm running a pretty low end setup, but it's serving the purpose for now while I'm still in college. Anyways, I have a surround setup of Kenwood speakers, and seperate sub and center running through a Sherwood RD-7103 receiver and a JVC XV-SA75 DVD player. My problem is, when I playback some DVD-Audio discs through the 6-ch input, some discs don't seem to be playing anything back on the front left channel, even though they are surround discs (even on the stereo track on these select discs, I'm only getting sound on the front right). When I try other DVD-Audios, any DVD movie I have, and some DTS CD's I have, they all seem to be working fine from all channels. Is there any logical explanation for this?
