I've solved the video footage error, and it's most bizarre. On the bluray version there's a bonus feature which has a multi-angle version of Outcry. If you watch this version, namely on camera 1, you will see James sing "Though you may stand upon my grave" exactly as the audio suggests on the main version, however he's in a completely different position on stage from the version on the main disc. This leads me to believe the audio is used from the multi-angle version whereas the footage is from the other night (this could also explain sync issues). What I find absolutely bizarre is that BOTH nights worth of footage for Outcry are on the disc, yet they chose to use video footage from another night on the main disc.
