But first, a note for TEROS: after a full power-down (and not reliably) the PHD-VRX may still show the program listing with all your programmed events, but not start them when they come due.
You do NOT have to delete and re-enter all the events! Just scroll through them, open each one, toggle the ACTIVE box OFF and then ON again, and click [UPDATE]. They will then record. Still a PITA, but less of a pain than re-entering.
WARNING: You MUST make all entries and changes to programs while the appropriate tuner is active! This IS a blatant bug - if you leave Tuner1 selected and scroll through, doing anything to the Tuner2 events will cause some of them to change stations, Time OR repetition class (weekly, daily etc.)!
So, set Tuner1 active, scroll through and toggle all Tuner1 events, then set Tuner2 active and toggle all its events.
TODAY'S OBSERVATIONS: about Recording History, reduction of number of program events, and unexpected recordings.
I have not used Recording History, and am not really sure how it works or what it was intended for. It DOES survive removing or reformatting the USB drive, AND power-down. Now that I've finally moved from 243.23.31 firmware to 243.25.43, I know that it does NOT survive firmware upgrading.
I had been finding that I had fewer and fewer available total recording slots! In fact, I was being shown a message saying that all my 28 recording slots were full (there should be 32, of course) even though I had only 20 events scheduled...? I got an inkling that something was whacky when some recordings were created though I'd deleted their events much earlier. Something was corrupted, but what?
NOTE: This MAY explain why I sometimes found the unit reporting schedule conflicts when I saw none on the listings.
Looking into the Recording History, I found it listing from December 2013 (when I switched recording drives) to about June 2014, when it apparently filled up and stopped adding listings. I was hesitant to mess with deleting the listings as someone had reported problems when they did that previously. (Anyone know more about this?)
Having acquired a second (heartily recommended) USB 3.0 2-Terabyte Buffalo DriveStation DDR (Price dropped $20 since last year), I copied all my saved recordings AND the "record" file (containing tile, position and indexing info) before experimenting, and made a hard-copy list of my programs. Then I upgraded the firmware.
Remember, if you move both the .NAV and .MPG files, as well as the "record" file, to a new drive, you will still be able to view, rename, play and delete your programs on the new drive. Without the .NAV and "record" files, you will only be able to view and play the .MPG files via the Video menu, and you will get (1) less precise and smooth indexing, (2) no saved viewing position, (3) only the original cryptic file name, and (4) no way to delete the files from the PHD-VRX. You can still rename and delete the files by plugging the drive into an ext2-filesystem-capable computer, either Linux or with an installed ext2 handler.
Et voila! The Upcoming Recordings and Recording History were empty, and I had my 32 program event slots back! (Again, programming first Tuner1 events, then Tuner2) I still don't know what the Recording History's intended use or actual functioning is... Does anyone have insight into how to safely delete entries from the Recording History?
I have not detected any changes in performance or function since loading the 243.25.31 firmware in late October. Anyone else?
