I could be wrong (it certainly wouldn't be the first time), but this appears to be a DVD from a different region. My UK DVD of POTA runs at 107 minutes, too - it is, however, exactly the same movie, but different regions run at different speeds, which is why I have to use a Region 1 disc when recording. I think the DVD you've posted a link to might be Australian (which is either Region 3 or 4, I think).
