You're right avl6211. I also have wetek play 1 with tuner based on avl6211. Is it possible to somehow extract drivers from one image and insert them to another?
Actually I have venz k1 or vigica s100 which is based on amlogic s805 with dvb based on aml6211 and tried with HD18Q image, all is ok but in the tvheadend I can not see tv adapters. Enabling dvb drivers does not help.
