This is a tricky problem, because a notion as abstract as "Notting Hill"
has no single concrete representation: if you buy a two DVDs of the
movie in two different countries, you may not have consistent timecodes
between them. Some scenes may have been removed in some countries;
furthermore, NTSC and PAL create slightly different timings...

If you read the UC about user generated metadata, the underlying
asumption is that both user refer to a common representation of the
movie, from a common VOD provider.
