Comment (by danielk):

 (In [10097]) Refs #1887. Fixes the underlaying cause of the invalid PAT in
 the DVB recordings which causes the reported crash.

 Multiple PAT tables do not seem to be precluded in the MPEG-2 spec, but
 seem to have been banned in DVB-S, DVB-T, DVB-C and ATSC. But they are now
 allowed in DVB-S2, and have been seen in the wild.

 Multiple PAT sections have always been allowed by the spec, but we haven't
 seen them in the wild.

 This extends mpegstreamdata to allow both multiple sections per PAT table
 and multiple PAT tables. This changes the interface a bit, hence the
 changes in the other files.

 I've left the ticket open because still haven't looked at having ffmpeg
 not crash on bad tables.
