Hi, I was wondering if any of you has used a video grabber to acquire and decode Teletext data. I just checked with the meteor, and the data lines are reasonably clean to store them on disk and attempt a decoding in software at a later time. The Hauppauge board might actually use this method. The (net) data rate is about 36 KB/s, although saving data to disk using Y only might require 8 times as much storage.
