TVHeadend - Channels losing Schedules Direct EPG if the channel names are not identical

Hello.

I have a problem that perhaps you guys might be able to help with.

I use the London Sky HD bouqet, on TVHeadend, to obtain all my channels and keep everything up-to-date.

I then use the Schedules Direct internal grabber to obtain EPG data

About 90% of the Sky channel names and the names used by SC are identical - this means that the EPG data automatically links with the correct channel.

There is, however, an issue with the remaining 10% - e.g. if the channel is BBC One and the SC data is BBC1, the two will not link up.

This is not initially a problem as I can manually change the EPG source for all the remaining channels.

The problem starts, when I have to restart my server - all the manually assigned EPG sources are lost and I have to add them all back again.

Could anyone perhaps suggest why this is happening and what I might do to solve it?
