Tvheadend

Regards to all,
I have a problem with 09c7 Vodafone dvb-c and tvheadend.

When I play the encrypted channel in VLC, the stream starts, but there is no picture or sound. In TVH, the stream is detected, in the Descramble column it is written that the key was found and in how many milliseconds. The server also shows that the channel is decrypted, but there is no picture.

I would like to mention that I tried the same line with Astra Chesbo and it works, so absolute oscham reader and oscham user work on astra cesbo, but not on tvheadend.

Does anyone have an idea how to solve this?
