Summary: this was a refurbished product. the on/off button would not work! I sent off for repair from panasonic. They could not fix? Sent a replacement product (refurbished) that does not work with the speaker system sent. Still waiting to get resolved.
Summary: After reading wikipedia pages, researching what in the sam hill all this mathematical architecture stuff is, i went with this model. Let me tell you, I was skeptical about having an expensive electronic system shipped to my house. In the end, it arrived a day early, in mint condition, and all together. Setup was as easy as 123. Whats more, we had no problems with any of the features or speakers.
Summary: I bought a SC-BT100. I have been very happy with the unit until the HDMI port broke and it had to be sent in for repair. I sent it in and was told two weeks. I called 3 weeks later to inquire as to the status and they said they couldn't find the unit and starting asking me all these questions, where I bought it, model #. Finally after 45 minutes it was located and they said I should have it in 7-10 days.
Summary: As a home theater working with my HD Tivo it's about the same as my previous stand alone surround receiver. As a Blu-ray player, the HD picture & sound are totally awesome!! The DTS-HD sound is to die for. While it's not a BD-Live player, that's OK for me. I would highly recommend this as a lower budget system.
