Also, this coming from a non audiophile, got use to the "Direct" sound, so I don't miss the impact from "Movie EQ". Hope you get it all figured out. I'm starting to enjoy mines more, I just need buy some speark mounts to correctly position my satellites speakers.
The manual states that in 'direct' mode with surround off you will get 3.1 from a 2.0 source (Pandora)
With 'direct' and surround on, you will get 2.1 from a 2.0 source.
With EQ on 'movie' or 'music' you will get 5.1(Not true 5.1) from a 2.0 source. (I think its like Dolby Pro Logic II)
I think it's not just an EQ and can do some DSP stuff like Dolby Pro logic II upmixing.
In reality, sometimes this is true that you need to use 'movie' or 'music' for 5.1 from 2.0, but most of the time I get 5.1 from 2.0 no matter what the EQ setting as long as surround is 'on'.
I found that some odd sounds/ hissing from the rear speakers happen when the source isn't DD/DTS, but with a proper source, the rear speakers sound great. Maybe it's different when the SB is decoding the DD/DTS instead of being fed a multi-channel PCM source.
Using rear speakers with different resistance than the original can cause a change in levels, but the level options can be used to set them properly. Different signal wires won't make a difference unless they are shielded or put through a filter either active or passive.
