Blank track names on DVD cause wrong display order
On some dvds, some subtitle tracks don't have a name (for subtitle tracks that are only used to translate some titles/panels that appear on the screen, for instance. The Starwars ep IV, V, VI DVDs are examples of this). As a consequence, VLC displays all the tracks titles in front of the first tracks, even if some of them were unnamed, creating mismatches between the named displayed and the actual track title.
For instance, if we have
1. English
2.
3. French
4.
VLC will display
1. English
2. French
3.
4.
The french track still being the 3rd one.
