I just learned about a Bug in the webremote plugin at some newer DreamBox Receiver.

If you press the Text Button for Videotext the Box enters the Videotext mode but you would be unable to exit. It is not up to DreamRemote and I'm unable to fix this. It also occurs if you control your box by using the default build in web remote by entering the IP Adress of your box into a normal web browser.

I will perhaps simply remove the Text button, even if I don't like this solution.

It affects so far the new Dreambox Models DM8000HD and DM7020HD.
At the DM7025 over here it works without problems.
