Mario,

Which it isn't of course :)

mkisofs
-dvd-video                  Generate DVD-Video compliant UDF file system

In case of a mini-DVD, the DVD drive considers it a standard CD-R (with 
whatever on it, it doesn't care), with the software side taking care of 
everything.

DVD specific ioctls will fail in this case, and should not be used.


I don't know how to solve the problem for you, I just want to take away the 
confusion of wether it has anything to do with your CD/DVD drive (you don't 
even need a DVD drive, CD reader will do, it needs to be fast enough to reach 
DVD 1x speed though, so CD x9 ?)
 
The software needs to understand that the CD-image is a DVD UDF filesystem.

Consider one example, usually if I have a big divx (from recording) to burn to 
a CD-R, and the size is matched to max out a single CD-R, I burn the divx 
directly AS the ISO, instead of putting it INSIDE an ISO image.

Mplayer will play it just fine (i.e. mplayer /dev/cdrom - and it will 
recognise it as a divx). Until now we still haven't figured out how to 
convince Windows (friend's place) to play them :-)

What does mplayer say about your mini-DVD ? With or without -dvd parameter ?

Let us know how things progress,
Cheers!
Dennis
