I've actually made some additional improvements in this area on a development tree which I am preparing to submit upstream. Most applications such as tvtime crop the area in question (around 1.5% on all edges) to behave comparably to a television, which results in users not seeing the top and bottom couple of lines. The teletext should be working (it was tested against a live source). Which application are you using? It's been my experience that the application support for VBI could be described as "crappy at best", so it wouldn't surprise me to find that there is an application level issue. Devin -- Devin J.
