[DVDnav-discuss] [PATCH] fix arbitrary wrong encoded file names in UDF file system

[Alexander Roalter]

This patch (as suggested in 
http://ubuntuforums.org/showthread.php?p=11254706) fixes an issue with 
newest Paramount DVDs (Thor, Rango) where a special video_ts.ifo file 
with bogus information is placed in the file system in a manner 
unpatched versions of libdvdread will use that file instead of the 
correct VIDEO_TS.IFO file, the result being an unplayable DVD.

The following patch uses the return value of the Unicodedecode to 
determine of such a non-transformable value has been encountered, 
dropping that file name.

Cheers,
Alex
