I am running the 8/20 firmware at present.
I've had my MicroHD set to local time, standby OFF, permanently turned on for a little over 1 month now. I have a mix of some weekly, daily, and once timers set. Most of them are METV, some are THISTV (same sat) a few have been PBJ (KU- separate motorized dish, through a diseqc switch) So far, (once I noticed that sometimes when setting multiple timers in a row it changes the default to CHANNEL instead of the default RECORD, I now double-check each time) since that point, all my timers have fired flawlessly. I do have a few where I set them to say 59 minutes instead of 1 hour, to give a 1 minute buffer between the following back to back timer.
Here are a few bugs I have noticed when setting timers:
1: As mentioned above, when you are say programming 3 timers one by one, 1 and 2 are fine, but the 3rd one about to be set will "magically" change the defaults from RECORD to CHANNEL. I set these by pushing the CLOCK button (below the Blue button) on the remote, it brings up the timer screen, and then just going through that and making changes as needed.
2: Say I'm tuned to METV (101w), and I'm setting those 3 timers above, since I'm parked and tuned to MeTV, you'd think the default channel in that timer-set screen would stay on MeTV right? Wrong! it sometimes magically changes itself to a random channel out of any of the 1,000+ I have in my list. This happens on all subsequent timer settings past the 2nd one. I then have to scroll through the list, trying to get back to MeTV for choosing (or whatever channel I'm setting). Instead of a scroll list, could this be set to have the Search channel list come up, like when you press the "List ok" button?
Observation: There MIGHT be some component of either being in "All Satellites" list, versus having that particular sat picked standalone/singly whatever you call it. I have noticed for sure, that if I am set to that sat in particular AFTER a timer kicks off, it defaults BACK to the "All Satellite" list.
In other words: You'd "best practice" to ALWAYS only set timers when you are in the "All Satellites" list, otherwise you are guaranteed odd results.
