Do you want me to get the "DVB team" (TM) onto #1049 ??
We need it to finish off #1485 properly (DVB scanning)

As Mark & I worked out, it is most likely that they rarely change their
PATs across all of their transports, and so quite possible that we think
we've seen the correct PAT, when we have in fact changed tranports, but
the new PAT has the same version number as the old PAT.

I've attached a further patch to this tickets that checks the tsid on the
PAT & if the tsid is different to the cached PAT then the PAT is not redundant.
