        No, what I meant was that the ivtv drivers don't support VBI
with the m179 card (it uses the SAA7114 decoder instead of the 7115).
I think I was able to make enough changes to the drivers to get raw
/dev/vbi working but not the sliced mode needed for embedding in the
mpeg stream.

        That's why I asked for someone else (with a PVR-250) to
provide a sample mpeg file (using the correct ivtvctl options or
using your patch).
