Recently, I noticed that my TV can record the current programme to a USB disk,
in the format of an MPEG-2 Transport Stream, received from a DVB-T network,
with irrelevant PIDs, for other channels stubbed out (although they appear in
the PAT) - which VLC will happily play. However, its header seems to be in a
format that deviates slightly from what Wireshark's MPEG-2 dissector will
dissect, so opening one of these files fails with "The file
"20151122_123105_[59 BT Showcase]_[This is BT Sport Showcase]" isn't a capture
file in a format Wireshark understands".

An example of an offending file is attached.
