I'm having problems playing the extra disc in the region 2 box set - any suggestions?
Maybe it's the cheapo Proline 2000 and the Playstation 2 players I own.

yep - and disney have no plans to re-press the disc

I had problems with this disc too - ht eonly player I could find that it worked on was the Sony 535 - so I ended up getting that player (it was a vast improvement over my old player anyway)

Sounds like it's the player rather the disk I'm afraid
