I've also got an old DVD player that plays VCDs, but not burned ones. Nor will it play DVDr or CD-R music. TR47 is right though, I replaced that with a new phillips last year for about $100 US.
I don't personally have the LOOK! bootlegs, but Rikter started an excellent thread on the bootlegs here: http://originaltrilogy.com/forum/messageview.cfm?catid=2&threadid=801
This should help you tell all the different releases apart.
