There are other problems, like the channel autoupdate picking data from
the wrong satellite. I don't think you can solve that without a plugin.
In fact Klaus promised to check the plugins in the tuning thread to see
if a channel can be actually tuned to and it is ready to be tuned. If he
manages do to it and at the same time doesn't block vdr responsiveness
to the remote I think it would be the best solution.
However, Klaus kindly reminded us that his day has only 24 hours (bad,
bad Klaus ;-), so you'll just have to be patient.
