libdvdread: no VTS_TMAPT ??

Hope this is the correct place to ask this question.  On some DVDs I have no
problems, but on others I get this error when I try to do something which
reads them such as tccat or lsdvd:

---------------

It then goes on to fail miserably, only extracting part of the DVD.
I *think* that libdvdread is generating the error, and as part of ogle,
hope this is the place to ask about it.  Ideas?

Thanks,
