The Killer boot I have also has a 30 min interview with Woo and Tsui Hark. Don't know if this is the same as what you listed above.
Otherwise the only other thing I can think of is the alternate commentaries on the FoxLorber DVDs. They have most of the same content discussed as the Criterion tracks, but with some different information and contributors here and there. IIRC Woo's commentary on The Killer is better on the FoxLorber than the Criterion, where he seems less enthusiastic.
The Criterion LD PCM should be the same source as the the DVD mono. Just imagine it in PCM versus lossy DD 2.0.
