Hi all !
Thanks for the very good answers , I used that trick on DM800se sim 2.2, I didn't like it.
I use Vu+solo2 tuner on usb ( GENIATECH MyGica USB TV tuner Stick T230C DVB-C T2 DVB-T HD ) , works very well .
The same tuner on the DM800se does not want to work , I installed the driver, I put it in and it doesn't want to be manually ..... under any circumstances .
