Try passing the -t iso9660 option to mount or (if that doesn't work) you
 could go so far as to removing the UDF support from the kernel.

If iso9660 looks enough like UDF to confuse the f/s typing logic, would
the problem go away if the iso9660 were checked first? It seems iso9660
can be mistaken for UDF, is the converse true?

In any case it can be set explicitly.

Good point, but I hope that if that is the case it would work as either,
and the UDF mount would have worked. Perhaps that also would have worked
with a bit of option support.

DVD ROM on 2.6

[Wakko Warner]

I'm trying out 2.6 on one of my test boxes with an IDE dvd drive.  I'm using
ide-scsi (I prefer scdx as opposed to hdx).  I noticed that any attempt to
mount a DVD movie (lord of the rings comes to mind) it mounts as UDF.  My
laptop mounts this same dvd as iso9660.

I've also been unable to play DVDs on this machine, but I don't have the
same packages installed as I do on my laptop.

I had a brain fart.  I was using -o instead of -t =(

I do have DVDs playing now on 2.6.0-test3.  I used ide-cd instead of
ide-scsi.  apparently the scsi layer didn't like it.
Buffer I/O error on device sr1, logical block 7651
Buffer I/O error on device sr1, logical block 7652
Buffer I/O error on device sr1, logical block 7653
end_request: I/O error, dev sr1, sector 660400

I would get tons of Buffer I/O errors and some end_requests like the above

I thought ide-scsi was broken?

I can't tell if this is in the ide-scsi driver or the scsi cdrom driver.  I
still personally wish that the ide drivers were modules of scsi instead of
being a seperate block device.  USB storage creates scsi adapters, ide-scsi
allows ATAPI access via scsi.  Why not do this for ide in general (if that
starts a flame war, please don't contribute =)

Probably because IDE and ATAPI are not the same thing. There are devices
which electrically connect to the IDE bus which don't speak ATAPI.
