PT xx just indicates that the uplinker of the transponder does not have a service name assigned in the tables. They could easily type in a service name when they assign the PIDs, but don't. Uplinkers often don't care about much about propagating correct information that us folks at home might like. Such as correct time, false encryption flags, default screen resolution flags and the one item that I see frequently missing the PCR (for AV sync)!
The A3 uses a placeholder name to log the service. Other receivers have used placeholder names such as CH xx, TV xx, Svc xx, etc.
