I have a Samsung 46" DLP HDTV television. I am using a Yamaha AV receiver and Polk Monitor speakers.(POLK Monitor 40 for front and rear. Polk Monitor CS2 for the center and a Velodyne woofer.) The problem I am experiencing is that when I am viewing any HD movie from cable TV, I get sound from the center, the woofer, a front and a rear speaker. I have to select five channel stereo To drive all the speakers. However, when I am viewing a DVD movie, I get surround sound from all the speakers. I dont know if I have a wiring problem or a receiver problem. Please help.

    If you get sound from 1 front speaker and 1 rear speaker, you may have it wired wrong. Even though you get all 5 from DVD, you may not be getting the correct channel in each speaker.

    that sounds like a wiring problem to me, also please note that Cable broadcast is generally not in the same high ress formats that you find on optical media (DVD, blu-ray etc..) so its never going to sound the same.

    Generally you should get A LOT of sound from the Center speaker and woofer, some sound from the front right and left, and almost no sound from the rear speakers.
    Very little information gos to them and you will only notice there presence if say like a plain or something comes from behind you in the movie.

    on a side note theres no real point to 5 channel stereo unless you just want louder volumes, if something is not mixed natively in 5.1 its going to sound better in what ever it was mixed in.

    My advice is just leave your AVR in pure/direct mode let it decode the audio in what ever native format its coded in for best sound.

    Also re check your wiring, if that dose not help call the support lines of Yamaha/your cable company or wait for some one smarter to post.

    Don't sell yourself short man, you pretty much nailed it. Very good post, and other than a wiring problem, this could also be the issue as well.

    You may have an issue where either you have the inputs from the cable box plugged in incorrectly, or you may have your speakers wired incorrectly.

    The first thing you should do is the test tone from the receiver. It should provide white noise one channel at a time and tell you which speaker should be making the noise at that time.

    I am using an HDMI cable between the cable box and the TV.
