I think that the bug is only related to the behaviour with the property
'chapter' that must be IMHO to 0 for the first chapter and not to 1.
And maybe a test in stream_dvd is provided for values beginning by 0.
But it needs some investigations, I've done only assumptions...

I'm sure only for a thing.. it crashes when the value is greater than
the max.
