I think I've found an issue in the tvserver configuration.
When I manually add a tvchannel I can't fill the details.

Steps to reproduce:
Start tvserver configuration
Go to tvchannels
Click "Add"
Fill in "Name" and click "Add"
There, select DVB-C, Ok
In next screen add:
Channel: 138
Frequency: 320000
NetworkId:0
TransportId:3
ServiceId:312
Symbolrate:6875
PmtId:3140
Leave provider empty
Modulation:Mod64Qam
Check "Free To Air"

Then click "OK", Error box appears stating "Please enter a valid network,transport and service id!"

The same happens if you select one of the channels already found at the channel scan, click edit, don't change anything, and then click "OK"

Edit: upon inspection of the FormDVBCTuningDetail.cs I see that the networkid may not be "0", but this is what the channel scanning returns, so I think this check could be relaxed to if (onid < 0 || tsid < 0 || sid < 0).

However when I fill "1" for networkid, no error message appears, but the form still won't close
