Comment (by reimar):

 So it looks like:
 1) the 2-byte packets are the EIA-608 compatibility packets
 2) the longer packets always start with a packet that has been a
 DTVCC_PACKET_START and then continues with all that have been
 DTVCC_PACKET_DATA after that
 In both cases, the data is unchanged compared to what is in the MPEG file
 except that any and all header and filler and control data (like
 packet_start vs. packet_data markers) has been removed
