It shouldn't matter how you mount UDF/ISO bridge volume. "Strange results if mounted as ISO, but not as UDF" indicate malformed logical format of that particular media. It's not some universal rule. > I think I've seen that specific symptom before, but I > might be mis-remembering. There is an universal rule, but it has nothing to do with file system. You can count on I/O errors when accessing .VOB files on content protected DVD-Video, unless you authenticate yourself with a player key.
