You'll use something like ISOBUSTER or install the UDF reader from the maker of the software that created the UDF CD.
I have heard about a UDF reader that can read a CD made on a XP system that the ME cd-rom wont recognize.
I have a cd with pictures that was made on a XP system, my ME wont recognize the cd when put in the cd-rom, but I can see all pictures on yet another XP system..... I believe after reading some things about this that the have a UDF reader to do so, but I have no idea where to find it or use it, any ideas ????????
