Now where it all gets weirder is that some forms of VCD (especially the
ones for philips short lived interactive stuff) have an ISO file system
on them but where sector numbers in the file system for video blocks
point to blocks that are not 2K data blocks but mpeg blocks that the
file system layer can't handle, so a VCD disk can appear mountable and
the like.
OK, but this is still mountable only from windows....... Is this ISO
filesystem hidden somewhere, or what? And that still does not explain
errors from xine, and the 8 megs that i actually can read using dd.
All after all - even if this disc would contain totally unsupported
tracks, with absolutly weird data, kernel should recognize it and
report something like:
cdrom: there are no tracks on hda i can recognize
(or something like that). If the errors do happen, it means kernel
thinks he can read the data, and he actually can't, yes? Is here
anything I can do to improve support of this disc under linux, or is
this just another hell-knows-what thing, the kernel implementation is
ok, and this is only some m$-dontated extension that prevents us from
accessing this disc? Even if it is, shouldn't it be implemented if it
is possible?

Thanks
