I've seen the same problem. The data seems to get corrupted when read
from te CD. When I mount it, I use the option cruft=yes and it gets a
little better, but the problem remains :(

That's what I do...

Same problem, same driver...
BTW I've experienced the same problem under NT 3.0 (don't yell at me, I
only use it because I HAVE TO, don't like it ;).
Could it be that the CD-ROM is faulty and they fix it by software in the
DOS driver?
