Hi, > Neither do I. Can e.g. dvdauthor handle subtitles at all?
Yes, most definitely -- although AFAIK "only" in vobsub format, it doesn't do any conversions. > Not as far as I know.

Certainly some pages are related to the program -- especially the subtitle pages (quite common in Germany -- not sure about other countries). > What makes things worse is that > teletext streams come in several varieties, and each of them may include > different substreams.

Fortunately, there is already a mature, free, not too bloated library which computes the rendered text pages: libzvbi. > Of course you also need to consider the required output format for DVD. > I haven't found any complete description yet, so anybody implementing > subtitles may have to use a trial-and-error approach (and will have a > lot of troub^H^H^H^H^Hfun). That was/is not really that hard. vobsub output for DVD is already in current ffmpeg, please check out dvdsubenc.c. I also have the conversion ready as an ffmpeg decoder (using libzvbi), so I can generate DVD subtitles from teletext pages. I'll try to see what I can come up with for dvbcut.
