I took a quick look at dvdbackup. From what I can see it only uses
UDFFindFile to get the sizes (in bytes) from the VIDEO_TS.*, VTS_* files.
This can be done by using DVDOpenFile, DVDFileSize, DVDCloseFile.
DVDFileSize returns the size in blocks. To get size in bytes just multiply
blocks with DVD_VIDEO_LB_LEN (2048).
This will work for all files except VTS_XX_?.VOB

I'm thinking of adding a DVD_VOB_Sizes() which will return the sizes of
all VIDEO_XX_?.VOB parts.
But I'll probably wait until after this release before making any more API
changes.
Anyone have any comments on this?
