The decoding of the OPCR field in MPEG-TS packets is incorrect. As described in
ISO/IEC 13818-1, the OPCR field is 6 bytes long. But the dissector skips 6
additional bytes.

The relevant code is at epan/dissectors/packet-mp2t.c:986.

Note that the structure of the OPCR field is identical to the structure of the
PCR field, so they can be decoded the same way.

The bug was introduced in git commit 4118256.
