From the manual of my Onkyo TX-SR505:
"The multichannel DVD input is for connecting a component with a 5.1-/7.1-channel analog audio output, such as a DVD-Audio or SACD-capable DVD player, or an MPEG decoder.
While the multichannel DVD input is selected, the Speaker Configuration settings are ignored, and signals from the multichannel input are fed to the speakers as they are.
On some DVD players, the signal from the multichannel subwoofer output is 15 dB higher than normal. You can change the subwoofer sensitivity to match your DVD player. Note that this setting only affects signals connected to the SUBWOOFER input jack of the multichannel DVD input. You can select 0 dB (default), +5 dB, +10 dB, or +15 dB. If you find that your subwoofer is too loud, try the +10 dB or +15 dB setting."
So, am I still going to have trouble adjusting for LFE, or is the Onkyo manual backward and "higher than normal" should read "lower" and the adjustments are to strengthen rather than soften output?
Also, the manual says if the multichannel component has a 5.1-channel analog audio output, don’t connect anything to the AV receiver’s SURR BACK L/R jacks. But it doesn't say what to do if the multichannel component has 7.1 (which the BD55 has) but only 5.1 speakers are connected (as in my case). Should I connect all 7.1 from the panny? If I connect only 5.1, will the panny output only lossy 5.1, or can it output lossless 5.1?
