Comment # 3 on bug 13238 from 
I've attached the relevant parts of the spec for PMT and descriptors.

The descriptors have a 1 byte tag followed by a 1 byte length field, followed
by length bytes. In the case of 0xA2 in this packet it is followed by a length
field of 1 followed by a single byte of 0.

0xA2 is in the User Private tag range and is not defined in the spec. Unless
Wireshark has more detailed knowledge of that tag it should simply skip over it
I think, or at the least if it errors in parsing what it thinks that descriptor
tag should be it should only skip that section and use the length field to move
on.

Thanks,
-Jeremy
