No, you're not alone.  So far, I've experienced two dead London recordings...
and it didn't matter what player I used. They were equally dead on my D5, my
dad's Sanyo, and a friend's unit.  And yes...all the Japanese discs have been
flawless so far.

Question:  Aside from the obvious "Japanese discs have a clear, raised hub
and come packaged in 8-prong jewel-boxes while German discs are uniformly
aluminized, flat, and come in 6-prong jewel-boxes (with that 'stamped hole'
look)", I have a disc stamped CSR (is this CBS-Sony? it looks like them) with
a (poorly-designed) three prong jewel-box.  What other designs are in use
now?
