So video1 is mainly being used for SACD & DVD-A, both of which would actually be falling to the 7.1 Direct input (which is an independent input), but it also has component video and coaxial digital connected. What discs are you using in this player that are "sticking" in PLIIx Movie? Are they DVD-A and SACD discs only? If so, it may have something to do with the limitations on digital outputs of those formats - SACD's in my Yamaha don't produce any digital audio output, whereas DVD-A typically downmixes to DD 2.0 I believe.
