Am I right that the system will know when a source is providing accurate 5.1/7.1 sound and then not re-sample (i.e. with pro-logic or whatever) - basically, it would configure it to what it's supposed to be? However, a lot of TV is just 2 channels... so I'd want it re-sampled to subwoofer and all the speakers. From what I've tested so far, it seems like A.F.D. MULTI is the best setting for TV. Does this make sense? What can you decipher?
A.F.D. mode 2CH Stereo
When multi channel surround formats are input, the signals are downmixed to 2 channel.
Presents the sound as it was recorded/encoded without adding any surround effects. However, this receiver will generate a low frequency signal for output to the subwoofer when there is no LFE signals.
Reproduce sound from any of the format to 2 or more speakers.
[DOLBY PL] - PRO LOGIC
Performs Dolby Pro Logic decoding. The source recorded in 2 channel format is decoded into 4.1 channels.
[PLII MV] - PRO LOGIC II MOVIE
Performs Dolby Pro Logic II Movie mode decoding. This setting is ideal for movies encoded in Dolby Surround. In addition, this mode can reproduce sound in 5.1 channel for watching videos of overdubbed or old movies.
[PLII MS] - PRO LOGIC II MUSIC

•When listening with sound fields that employ the virtual speakers, you will not be able to hear any sound coming directly from the surround speakers.
• This function does not work when: – signals with a sampling frequency of more than 48 kHz is input. – the multi channel Linear PCM signals are received via an HDMI IN jack.
• The sound is not output from multiple speakers depending on the source.
• Depending on the disc or source, when you select “AUTO”, the beginning of the sound may be cut off as the optimum mode is automatically selected. To avoid cutting the sound, select “A.F.D. STD.”.
•When the input signal is multi channel source, Dolby Pro Logic II MOVIE/MUSIC are canceled and the multi channel source is output directly.
•When the bilingual broadcast sound is input, Dolby Pro Logic II MOVIE/MUSIC are not effective.
•Multi channel Linear PCM is not available for “P. AUDIO.”
• Depending on the input stream, the decoding mode may not be effective.
