Yeah, this is tough. You could maybe convince the rep that because the "AVCHD backups" have a decidedly higher intrinsic value than the Laserdiscs, the fact that they are bundled as a freebie extra is a ruse--they are demonstrably of much more value than the Laserdiscs, and their description as a "backup" is false and misleading.

Then to explain why they are of more value, you can say that have vastly superior video quality, audio quality, AND they can easy play on a modern PC or home theatre setup, whereas the Laserdiscs require unusual equipment for playback, and still look like crap. Furthermore, they are bootlegs, so shut the auction down.

Heck, you could even use your little image of Luke through the years of various home video releases to show how these "free backups" are the real thing of value in the auction, and that they are not at all a backup of the Laserdiscs as described.
