I just rented these 2 DVDs and is this common on a Dolby Surround Sound 5.1 home theater system- I hardly heard anything on the back (surround speakers). Best of Show I gave up on after 15 minutes- I was bored but hardly heard anything at all on my back speakers- was this because there wasn't any background music. Looney unes with Brendon Fraiser only had occassional sound effects come from the back and I wasn't impressed. Is this because I have a cheap home theater system or are a bunch of DVD's recorded so that there isn't constant sound coming from the back speakers. Any input would be welcome on this.
