tried that too but still nothing...i'm really getting crazy about this...
don't know if it helps if I try to reset the receiver to factory settings?

FINALLY.... got it solved.
The solution was to download a new bouquet (multisat) channel list after that it worked like a charm (with a new list even my old list worked).
About the disecq configuration the correct way for the disecq BB command is port D. So to sum it up if anyone will have similar disecq problems:
commited disecq command AA equals to PORT A
commited disecq command AB equals to PORT B
commited disecq command BA equals to PORT C
commited disecq command BB equals to PORT D
Hope this post will help someone else.
