Sounds like they're possibly all Asian bootlegs. The first two have extras from the Definitive Collection laserdiscs. But again, screenshots of the menus will definitely help to positively ID them.

I can tell you that they're going to be very poor quality compared to the September DVDs, though. In fact, all the Asian bootlegs are pretty dismal even compared to more recent fan preservations. But no fan preservation outside of maybe the X0 project has a chance of even coming close to the picture quality on the upcoming DVDs (despite that set's appalling lack of anamophic capability), because that transfer will be off an original laserdisc master that none of us have access to. The fan preservations do make up for that in other ways, though.
