Just throwing in an update on using a timed reboot to keep PSIP data populated and up to date. Shortly after I started experimenting with this I noticed that the clock was setting itself 5-6 minutes slow several times a week following the morning and evening reboots. For the last 7-10 days this hasn't been happening, and the clock has been setting itself fairly accurately, usually 15-30 seconds slow, which has been my experience for years. The interesting thing is that the larger time discrepancy started occurring right at the time local stations were doing their repack and sharing shuffling gig. One local company is operating 6 channels, and the clocks for all of their channel's are 5 hours and 8 minutes behind. I can't help but think that this had something to do with my DVR+ clock running 5-6 minutes slow. But in every case, the clock on my DVR+ returned to normal approximately a week after each of these repack/shuffle events. It was almost like the ripples on a pond spreading out and then subsiding after a stone was tossed in. We've got a few more of those repack events coming up, so that should provide a good indication as to whether there is a connection or not.
But as it stands now, I'm really loving how using a timed reboot is working. All the channels that provide PSIP data (some LP stations only display "Unknown Event") are populated because rebooting initiates a full channel scan. Using dummy recordings tends to only keep the channels recorded up to date. Timed reboots also eliminate the need for the occasional reboot to flush out and clear memory leaks. The only thing I have to remember is to keep my Samsung TV source input set to the TV, and not HDMI1, which is the DVR+ input. Setting the TV to the HDMI1 input results in my TV powering up some of the time during the reboot.
So all in all, I have to conclude that timed reboots are superior to dummy recordings when it comes to keeping PSIP data up to date, though both methods have their advantages and disadvantages. The biggest disadvantage to timed reboots is that there is a brief window where a recording will cut out or start late if it overlaps with the time set for a reboot. A second device could cover that for known upcoming recording events, but if you are out of town or because PSIP data only goes out about 72 hours at the longest for some stations (PBS), vigilance is necessary to plan for these events.
