True, PL II is only available when decoding two-channel sources (cable TV, video tapes, CD's, or DVD's with Dolby 2.0 tracks) -- the same times that the old Pro Logic works. Standard PL II provides 5.1 only, it does not support a surround back channel. The Outlaw 950 (and several other new pre/pros, including the Rotel 1066 and the new Fosgate) uses Cirrus Extra Surround in addition to PL II to provide that -- similar to the Zoran-provided Surround 6.1 that the 1050 uses for Dolby Digital 5.1 tracks.
