Hi, I've noticed this too, but with the STV0299. I can lock to all signals around a symbol rate of 27500000 , but not to any which have a much lower one. I've got a feeling I'm going to have to look at the TT driver to get the exact settings as well for that. -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.
