[linux-dvb] Re: Problem locking transponder w/ low symbol rate

[Frantisek Bocek <bocekf@iol.cz>]

Hi,

I had also a similar problem.
It was a channel with SR=13333. It locked succcessfully under Windows drivers,
but not at all under Linux (note that I entered exactly the same values of SR, FEC, FREQ etc.)
May be a bug which affects only a certain SR range?  ( symbol rates as 6111, 5632 and lower seem 
to work fine for me)
I looked at the driver's source, unfortunatelly the computations with the SR 
are something very ununderstandable for me ;-)

Regards,
Frantisek
