Have first tested the original Software (Win 7, Lenovo ThinkPad T530), but somehow that did not work as I introduce me.
Knows what was no longer exactly the problem.
I called the manufacturer and the friendly man from the support gave me the same recommend the Windows Media Center to use.
From there everything was fine.
Switching works quickly and without problems, the picture is very good.
For 15 to make its (in my case) laptop for all TV.
Would I buy again.
