I'd considered getting a small sold offset with Ku lnb for X4, depending on what you're looking for, I think it is worth it.
Regarding your 920 - are you seeing X4 as a selectable satellite? Mine didn't because it needed a sw update which I had to send the unit away (to ATS) to have done, the update took my unit to version 6D and then X4 worked.
