I've just fixed a place where this error could occur.
The bad thing is that nothing has changed for this screen since ages...
Two questions to you all which might help me to find the reason:
1. Have you all been users of TV-Server before?
2. Are your all using MS SQL Server or did it happen for MySQL as well?
I have used TV server for a long time now, and tried many different SVNs.
I have always used MS SQL.
SVN 18436 is the first one I have noticed which allowed import of old recordings. Maybe this is just because I have not been very observant!
Thanks for looking into this.
