Do they even have a CRC? In PES, the CRC is optional and AFAIK mostly
not present.

FEC information is already processed and removed, otherwise the TS
packet would be 204 bytes long... But the FEC doesn't protect you from
occasional bit errors (neither does CRC32, btw, it just makes them less
likely).
