Page 1 of Help on Toshiba SD100 player (disc probs)

Hi there, I recently got Transformers: The Movie and have a problem with the disc (or maybe my player?).....I don`t know if anyone out there is familiar with the disc but it starts with an intro before the menu comes up. The problem is that there is no sound at this part or any of the othere special features but the main feature is fine. I replaced the disc 3 times but they all had the same problem. I tried the 3rd disc on another machine (Toshiba SD2109) and it worked fine! Tried calling Toshiba but they couldn`t help me, so I thought I`d try someone on this forum before trailing the machine round every repair shop in Edinburgh. Any help or suggestions would be appreciated.

Oh yeah, had a similar problem with Taxi Driver: the disc crashed when the layer changed, this happended on other machines too though....thanks.
