I have trouble tuning in to the channels on Astra 4A at 4.8°E freq. 12034 H. fore example TV1000 Nordic. All other channels on the same satellite (that is in my subscription) work.
I have checked the tuning details on this site and they were wrong for those channels after scanning. But i can not get them to work even after editing them.
When i try to tune in to one off the channels i get an error message "No signal".
Is there someone who can help me with this?

Well.. now it works. After a few "Update satelite list" and scans it works. :sorry:
