Eek! The DVR didn't record last Friday night's Battlestar Galactica!

I've asked the poor hubster to try to figure out what happened, so that it doesn't happen again tomorrow night. Meanwhile, I've read the episode summary on SCIFI.COM. Under the circumstances, spoilers, after the fact, for last week's episode would be appreciated. Thanks. (I assume that Baltar turned out to be human--it would just be too easy to explain away his behavior if he were a Cylon.)
