Mount DVD While Preserve Upper Case File Names 

http://www.linuxquestions.org/questions/showthread.php?t=391530

To maintain maximum compatibility, I write my DVD file names as FILE1, FILE2, etc (ie, all in upper cases). But after burning, when I mount it back I get file1, file2, etc (ie, all in lower cases). Is there any way that I can prevent this, ie, have my upper case file names preserved?

Specify UDF as the file system when mounting instead of ISO9660 and you'll get all uppercase file names.
