This patch definitely fixed the output ES bitstream for teletext packets
and teletext descriptor in pmt table, because I tested the output stream on
samsung tv set with using DVB-T signal generator. And I analized hex dump
some teletext packets in output stream. But there was a problem with
interleaving teletext-subtitle packets or calculation pts(and seems for dvb
subtitles too).
