Thank you for the config file, I have been away from home since then.
I found out the cause of this issue..maybe it can help other people not generate these issues.
It happens when you select a channel that has zero transmissions.
eg. When I perform a scan for Sky UK, it returns multiple entries for some channels like comedy central.
If I try to access these channels one at a time it generates the errors.
I have to access them to see which ones are valid so I can add them to my favourites etc.
I hope this is of some help to you and some users
