Tvheadend

Hello,
I have got a Wetek Play with DVB-C/T2 tunner flashed with OpenELEC in the NAND.
I use TVH in my PC with a TBS6221 to watch my DVB-C Annex B (J.83 B) provider without any problem... but with Wetek Play using exactly some config it didn't lock signal. I asked in Wetek and OpenELEC forum without responses. THe mail support of Wetek Play said the problem could be TVH... I don't think so.
I'm using OpenELEC 6.95.3 and here is the log:

2016-06-15 02:03:01.001 mpegts: 375MHz in Cable - tuning on CXD2837 DVB-C DVB-T/T2 : DVB-C #0

2016-06-15 02:03:01.001 linuxdvb: CXD2837 DVB-C DVB-T/T2 : DVB-C #0 - failed to tune [e=Invalid argument]

WIth the some config in my PC work.
For example:
Delivery System: DVBC/ANNEX_B
Frequency: 375000000
Symbol Rate (Sym/s): 5360000
Constellation:
QAM/256
FEC: AUTO

Thnaks for your time!
