I don't understand what the problem is and how you intend to fix it?
There is no such thing as a "subtype" in the PMT. There are often
"descriptors" though, used to provide different kinds of metadata for
the streams (check the MPEG and DVB docs for more info).
Different stream types are used in different parts of the world. E.g.
I'm getting AC3 streams with stream type 6 and an AC3 descriptor, but in
the US they seem to have AC3 sound on type 0x81 (IIRC) and no
descriptor. I think subtitles are normally on type 6 but I don't think
they *have* to.
