[linux-dvb] TT 3200: corrupted stream/no lock depending on the transponder

[manu]

	Hi all,
I can receive from 4 transponders (DVB-S): 11093, 11555, 11635, 11675 
MHz.
any channel on 11093: fast lock, perfect picture.
any channel on 11555: lock a bit slower and corrupted stream (lots of 
blocky artifacts, myhttv complains about corrupted stream)
any channel on 11635,11675: no lock.

I found that doing szap a few times (5-6 times) in a row would lock 
solid for the 11635 and 11675 transponders.
Is this something known?
Bye
Manu
