Yep; many cable companies do this -- channels < 125 or so are analog. > The main exception for me is the > reason I signed up for digital - BBC America - which, I am fairly > sure, > was transmitted as digital.

Yep. VBI == Video Blank Interval > I assume the ones recorded from the analogue channels will have also > recorded the video lines with the subtitles in? Not necessarily. AFAIK only Myth has the ability to record VBI data and convert it to subtitles for display afterwards. I doubt ReplayTV or Tivo can do this. (NB- Myth only supports this currently for analog framegrabber (bttv) cards), though support the VBI interface on ivtv cards is maturing, so Myth may support them at some point, too. -JAC _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
