I am interested in the concept of "virtual tuner". how is this done ?

Hi. I am having the following problem with subtitles (teletext) on a DM800. When I record a movie, I can play it back with subtitles just fine, if I use Dm's player. If i try to play the TS file in VLC, no subtitles are shown.
A little playing around with ProjectX, which is a utility to de-multiplex a TS stream, shows that the subtitles are present, but they have incorrect timestamps, they all actually have timestamps of 00:00:00, which is why VLC cannot show them.
I believe this to be a bug in the teletext handling software. The same problem also appears, if I stream from the DM to a VLC player : The teletext stream is shown to be "present", but no subtitles display.

any ideas ?
