I do have too many tabs in the TV-Channels Configuration.
I do have my channels correctly configured and can preview them. (I had TV-Server REV15649 installed and Preview worked, now with this Rev Preview also does not work, althoug these channels were found by the channel search)
In My TV there is no Channel. I can not activate the TV.
What is wrong? Which is my fault?
Thank you

Hi!
Dont know if this helps but...
Are channels mapped to any TC-card?
How does it look in [TV Groups]? You can always delete groups there if you don't want them.
... or are channels mapped in [TV Groups] -> [Mapping]?

I do not have any groups. These tabs are empty, all of them excluding My Channels and All Channels
