I didn't find anything about that problem in this forum so I start a new new thread...

I did a normal satellite scan, all channels have been found and were shown correctly in the channel list. When starting ProgDVB the next time many channels disappeared from the list. Some of them got visible again when changing the sort criteria of the channel list, some stayed invisible.
All channels are visible again after another satellite scan although they are were not found as new channels.

Any ideas or solutions? Thank you!

This is a bug in Versíon 4.83 ....fixed in 4.83.2 ....are you sure using 4.83.2 ?

Execpt of this i can´t reproduce this here in 4.83.2 ...all fine...
