Comment(by vkelim at bigpond.com):

 I have recorded two examples in MythTV. Unfortunately, the recordings are
 both half an hour long (an SD, and an HD recording) and both exceed one
 gigabyte in size. Examples of the problems occur within the first two
 minutes. Sorry to trouble you, but please advise me how to truncate the
 .MPG file in such a way as to preserve all necessary information.

 The HD recording shows a straightforward example, MythTV plays back the
 recording exactly as I saw it on 'live TV' at the time, with incorrect
 Teletext background colour decoding.

 The SD recording is interesting, because MythTV plays back subtitles
 completely differently to the way I saw it on 'live TV'. Instead of
 showing Teletext subtitles, it shows smaller (and I think more
 appropriately sized) white subtitles with black outline. No colour coding
 is preserved at all. However ProjectX shows that Teletext subtitles with
 colour coding can be decoded from the MPG stream.

 Cheerio, David.
