Missing a lot of guide data

So I switched to a Yagi antenna as the reception on my previous antenna was laughable.

But now even though the channels are coming in clear, I am missing guide data

How do I solve this?

On the DVR web UI click the circle refresh icon under your HDHR.

Wow. Thanks.

I am considering changing my antenna. Which yogi did you get?

RCA Yagi.

Thanks. Any particular model?
