The Teletext function of Win-TV can be improved significantly.
It's now quite unstable, causes hangs, displays frequently wrong charactersets and is slow.

Often it's said to be caused by the WDM-drivers but ...

The same function used with Dscaler (same TV-card Medion 7134) is fast, stable, buffers pages and subpages, you can click the numbers on the screen and has bottomfields which can be selected to switch thru the pages. That's what i like.

Success.

Dscaler doesn't use the WDM Drivers, it uses their own drivers that work directly with the hardware ( please remember that : if there is a problem with their driver it can damage your tv card )

Cyberlinks Powecinema 2 (came with the TV-card) has also the nice Teletext features and works stable and satisfactory. (But less quality on the TV-function)

Do they use WDM-divers as well?

For the Teletext function they work directly with the VBI Stream which contains the Teletext information and not the DirectShow Teletext Filters through the WDM Driver.
