Quick audio question 5.1 v Dolby Pro Logic
I'm doing well for questions in this forum recently 
Just goes to show how good you all are 
Just reinstalling a PC and have to choose a sound option for an ffdshow codec for video files (CCCP audio pack). The applicable choices are:
3/2 + LFE 5.1 channels
Dolby Surround/Pro Logic
Pro Logic II
Which is the better option?
(I have a 5.1 DTS audio out via Coax SPDIF from a X-Fi card)

Ohh - a question I know the answer to!
The original Dolby Surround was 4 speakers - stereo at the front but mono through both of the back speakers.
Pro Logic added a front centre speaker channel but the rest was the same. My first amp was Pro Logic - bought in late 1993.
Dolby Digital 5.1 was 5 proper channels (e.g the back speakers were stereo too) and a .1 base channel for low frequencies.
DTS was similar to 5.1 but less compressed (I think)

Leaves more room on the DVD for extras.
