Nothing positive happened until the late overnight (when it finally grabbed guide data). After 30 minutes, it still had nothing, but I banked on it updating overnight. It seems okay.
I have to wonder why it wouldn't record anyway. It would be smarter to capture PTAT whether it had the guide data or not. In fact, I couldn't even create timers for shows that actually showed properly in the guide.
Maybe someone will see this and get it fixed in a future revision. I wish it would just tell me 'The guide needs to be refreshed. This will take 10-15 minutes' and give me a yes/no dialog.
