Just wondering what actually happens when I play a 5.1 mix off a blu-ray disk considering I only have 2 front speakers. Obviously on my AVR I only have the front L+R selected as large and the remainder to off.

Does the sound from all channels condense into the 2 fronts?

Also, will there be any noticeable difference between say a regular DTS track and a DTS MA track with this set up? I ask because my current receiver doesn't have HDMI inputs, so I would have to upgrade my receiver to take advantage of the lossless formats.

Cheers guys,
Adam
