That's good news: it means the Pal can keep the guide updated (and probably the clock too) even if you generally keep the DVR on! It doesn't need to be in standby, contrary to my earlier guess.
I'm still trying to figure it out! I turned one off, left the other on all night. This morning both had similar partial guide info, for example KDFW 4 guide info was missing on both until I manually tuned to that channel.
That sounds like the problem several others have reported after TVGoS went away. But it's not consistent: neither of my Pals have experienced that problem, and I never did a factory defaults reset on one of them; just a double reboot.
We do know a factory defaults reset (with an invalid Zip code) is needed if the TVGoS station is still sending time packets. If that's not done, info saved in the Pal's memory will let it lock back onto any TVGoS data from that station. But since TVGoS packets ceased, that saved info seems to be doing no harm in my case. But like I said, apparently it's not consistent between Pals, so you may need to try the factory defaults reset.
Last night I did an experiment: I tuned to "The Ten Commandments" on WFAA/8, so tuner 1 should have been on channel 8. I then started recording it, which should have tied up tuner 2 also. I checked the guide status - KDFW/4 went out to 7 AM - then put the Pal in standby to release tuner 1.
Later I turned the Pal back on. Channel 8 (the channel I'd been tuned to) started playing, and the recording was still in progress. I then checked the guide and channel 4's info had been updated: it now went out to 10 AM. So it appears tuner 1 was used to scan channels while the Pal was in standby.
If that's correct it means the Pal can keep the guide updated if either tuner is available. Presumably that would keep the clock synchronized to PSIP also.
But I don't think I completely nailed it yet. Since I started recording from a live broadcast rather than a timer, it's possible the Pal's tuner allocation was different: it may have used tuner 1 for the recording (and would have used tuner 2 for live viewing had I switched channels). So to be sure, I'll repeat the experiment with a timed recording and see if that makes a difference.
