My questions concern wiring my HT. From what I've understood, it's a good idea for max video/audio quality to minmize the number of connection between the A/V source and the output device (i.e., hook the video of a DVD player directly to the TV, rather than first to the receiver and then to the TV). I've heard there's less potential for signal degradation if done this way. If this true in general, or does it depend on the quality of the receiver? Also, if a audio source only has normal RCA outputs, do most receivers upconvert the sound to digital, or can the receiver only "do it's best" to try to replicate a digital effect? Thanks. (BTW, I've also posted this in the "home theater basics" section of this forum - hope this is OK).
