[Dvdrtools-users] DVD with Joliet?

[Alan Dayley]

I am having a nightmare of a time creating a DVD that will play properly.  
Testing on 5 players shows at least 2, sometimes 3, that will not play 
the DVD.

I have a DVD-R that was created on another system last year and works 
flawlessly with all 5 players.  I have compared it's content with the 
disc I have made.  The only difference I can see is that the DVD that 
works reports "Joliet with UCS level 3 found" in the output of "isoinfo 
dev=/dev/dvd -d".

The "-dvd-video" option of mkisofs ensures that the VIDEO_TS.IFO file of 
the DVD is the first file available and that all the other files are also 
properly sorted.  However, if this option is set and the "-J, -joliet" 
option is also set, "-dvd-video" disables the Joliet extension 
generation.  Attempting to use the "-sort FILE" option along with 
"-joliet -udf" in an attempt to duplicate "-dvd-video" with Joliet has 
failed to get the files sorted properly.

So, my questions really are this:

1. Is there any reason to believe that some DVD players will fail to play 
a DVD without Joliet extensions or am I chasing a red-herring.

2. If Joliet can effect play of DVDs in some players, how do I use mkisofs 
to create a properly sorted DVD .iso with said extensions?

3. If I am asking the wrong list for this information, please tell me to 
buzz off.  A pointer to the right venue would also be appreciated.
