How can i access videotext data from my tvcard (terratec tvvalueradio)
I can read it using the software delivered with it. But i want to use to read in some data from specific pages and put it in an excel worksheet. Now i have to type them over. Are there sdk's for this goal?

You should look for DirectX documentation on:
* Line 21 Decoder filter (Closed Captions)
* World Standard Teletext

does not look simple to me. Isn't there an complete example? Even a c c++ example would be helpfull as msdn confuses me.

In DirectX SDK seems: DDrawXCL, PlayDVD, DVDSample, AMCap are impements some way or another teletext/closed caption support. - But I have not verified what.
