Media Portal TV-Server if Tuning then slow

[Vlaves]

Hallo,

I hope you can help me to install MP with TV Server, so that it is working

I have installed MP as suggested. First I have installed MP final, then the SVN-Snapshot listed here.
After that I have installed SQL-Server Express and then the TV-Server and the Plugin, just done everything
suggested here http://wiki.team-mediaportal.com/TV-Engine_0.3

When I go to the TV-Server config and go to manual Control I can Tune some channel there and it is Timeshifting.
If I open MP and go to TV I'm not able to turn on TV nothing happens
There are no Erroro Messeges or anything else

If I leave the Server in manual control Timshifting and connect to the Stream I have some Picture
in MP, but then changing channels is very slow.

Here is my config:
