DVB-S2 and SR 22500

Dear all,
I've got an issue when trying to receive PI6ATV with DVB-S2 and a SR:22500. Minitiouner has a lot of noise and PLL is not locking. With normal DVB-S2 SAT receiver it works ok. DVB-S2 with lower symbol rates is working ok. Is this a known behaviour? I'm using v0.8s.
Thanks
