Blow up while trying to schedule a recording

[wtg]

I tried the schedule a number of selected recordings and noticed "Let the Right One In" failed even though there was nothing scheduled for it's timeframe. I then selected it alone, clicked Record and received the following error:
[h=2]Input string was not in a correct format.[/h] Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.FormatException: Input string was not in a correct format.

Actually, I was mistaken: there was a recording conflict so it's proper that it didn't record. The blow up however was less than desirable.
