Make sure you're mounting the DVD as a UDF file system, and not as an ISO 9660 file system. Mounting a UDF file system as ISO 9660 gives strange results (rather than a complete failure, which would have been more useful). I think I've seen that specific symptom before, but I might be mis-remembering.
