[Marcel Mol]

libdvdnav | branch: master | Marcel Mol <marcel at mesa.nl> | Sat Aug 16 00:36:01 2014 +0200| [298139d90b5736afef4bef4c7f4ae6a895e57bde] | committer: Jean-Baptiste Kempf

Fix for Unknown command type handling

Some DVDs seem to use command type 7 for something.
But it will hit the 'Unknown command' check, resulting in asser(0).
I.e. DVD refuses to play.

By removing the assert() call the DVD seems to play fine.
This patch removes the assert and corrects the error message
(it is a 'command type', not a 'command')
