problem in progdvb 5.15.09 in vista x64
iam used vista x64 and progdvb 5.15.09 x86
the problem
i whant delet the channel list by go to
channel list then
Remove channels from list
and select the sat. and then ok
no found any change the channel is still found not deleted ?
the channel list in
C:\Users\user01\AppData\Local\ProgDVB\Channels

The channel lists (ChannelList*.tree) don't contain the central channel database, they work quite like link collections to it.
The data base is in Channels.dat

But if wanting to remove a bird from Channels.dat completely, just rescan that with no LNB connected, or with LNB power off. Then all stations on it should be found 'Lost'. Allow to delete.
Else delete the Channels folder content completely.

or use ProgEdit

when delet all file in folder Channels
the tab sat (not found )

Well, I would not suppose a tab to show up, if you don't have more than one list.
Right click it, to open it's properties and get to know, what kind of list this is, e.g. dynamic or favs.

Generally, any list showing up there is not the central database itself, AFAIK.
