Will all of them work ? Can I suppose yes, since the current driver only supports the tuner and the frame grabber. The teletext version (I think I have this one, although it was not specified) has an additional chip (SAA5246 if memory serves) to do teletext decoding. Maybe the "radio" version also has a modified tuner to get FM radio. > I get the Teletext (or any kind of Videotext ?). Is it also possible to > get the radio part with FreeBSD ? on my FreeBSD web page http://www.iet.unipi.it/~luigi/FreeBSD.html you can find some code that use data coming from the Bt848 (i.e. the "standard" card) and software decode them to extract teletext information. You need the modified bt848 driver also on my page, and possibly a lot of memory and CPU, but in principle this lets you get teletext info as soon as they come in. If you want to write support for the 5246 (which is not hard, I just did not have the time to) you need almost no CPU and memory, but the system is much slower since you have to ask for pages (max 8 at the same time I think), wait until it comes, and then download it from the 5246.
