Hi,

after Telenor switched from Thor-2 to Thor-5 (0.8W) no lock is possible with 
multiproto(-plus) and TT S2-3200 at these transponders:

TV4 HD;Telenor:11341:vC34M5O35S1:S0.8W:25000:512:0;641=sve:0:B00:1405:70:42:0
CANAL+ FILM 
HD;Telenor:11421:hC34M5O35S1:S0.8W:25000:513:644=eng;645=eng:0:B00:3306:70:14:0
Nat Geo 
HD;Telenor:11434:vC34M5O35S1:S0.8W:25000:512:640=eng:0:B00:3806:70:38:0

I'm 100% sure that this problem corresponds with switch from Thor-2 to Thor-5 
as it appeared exactly at times when switch was announced by Telenor. 

Regarding to official document 
http://www.telenorsbc.com/upload/PDFS/DVB-S2%20Transponder%20FEC%20Change_280208.pdf 
two changes were implemented - FEC from 2/3 to 3/4 and switch off Pilot.

On the same HW under Windows it is running ok.

If somebody could point me to any direction I'll glad to cooperate in 
debugging.

Regards,

Ales
