[linux-dvb] TT-3200 (DVB-S/S2) bad reception/no lock issue

	Hi all,
I already reported on that sooner, but now I have a log (with stb0899 
verbose=5) so I hope it makes it a bit easier to debug.
Still the same behaviour: one transponder (freq=11093 MHz) is ALWAYS 
perfect (fast lock perfect picture even with bad weather) and for 3 
other transponders (11555 MHz as in the log, 11635 Mhz and 11675 MHz) 
the lock is much less frequent and if it locks the picture is much 
worse even in not so cloudy weather. It is as if the card was much more 
picky with the other 3 transponders. Is it normal to have such 
discrepancies on the same sat?
Sometimes just locking on the "good" transponder and then switching 
back to a bad one gives good results: good lock and better SNR and 
picture (seen in mythtv).
Anyway here is the log, I hope this is of some help.
Bye
Manu

May I add also that rmmoding budget_ci,budget_core,stb0899 and then 
modprobing them back gives better picture/locking sometimes.

Any thought on this? InMythtv, going to a channel on a goodn 
transponder and then switching back to a bad one will give a lock and 
better picture, so...

Just out of curiosity:
Could you please try to set the channel frequencies in the channels list to
about 4MHz lower than they are currently? (e.g. 11551MHz instead of 11555MHz)

Finally someone gave me the good idea (thanks Dominik): I added 4MHz to 
the tuning frequency and now, AFAICT every transponder works great. I 
must also say that I have patched my multiproto tree with Dominik's 
patch, but I am not sure that it changes results by so much.
Anyway, things now look much better!
Bye
Manu
