Showtime won't play any video files on a DVD for me. It does show the files but without any codec information and when I try to play them it says

"Unable to open resource file:///dev_bdvd/... Short File"

Additionally, when I try to copy them to a HDD with a file manager like the one built into Multiman it does absolutely nothing after the prompt.

The files work if I put them on a flash drive - I am on Kmeaw CFW 3.55, is it because of some problems with the file system of the DVDs (UDF) or am I missing something else here? Hopefully someone can help me, thanks in advance!
