Problem with satfinder in Ts 3.0 image

Hello,

I have a dreambox 800hd with Ts 3.0 installed

When I use the satfinderfor SD or HD QPSK, works fine

If i use it to check frequencies Hd 8PSK never detects signal even when i have channels working on those frequencies....

What is the problem?

There is another plugin for this purpose?

Thank you
