Not enough information to speculate on the reason or cause. Maybe try reloading the most current firmware, perform master reset, power cycle then rescan 97w. After setting your timers in the "ALL Satellite" mode, leave the channel list in the "All Satellite" list mode and verify that all timers are firing. If not, try a different drive.
As I recall, you are only using Thumb drives. If I ever have had DVR issues on any STB, it was much more likely with thumb drives. Thumb drives typically do not have buffer and often very low throughput.
Personally, I would rather run the STB on straight 12vdc than through an inverter. As long as the voltage doesn't drop much below 12vdc, it should operate fine.
Very unlikely to be heat related.[/QUOTE
Last item first -- The inverter line was already run to the 'conditioned' room. DC line was not. But same symptoms with both.
Re loaded software from new download to USB stick to upload to computer; did master reset and power cycle. tried to load database -NO GO- repeated upload and M. reset, P/Cycle then Scanned in 97W as my database file seemed corrupted. Reset the clock and timers. Forgot to take of GMT. Recorded OK this AM, except started 22 minutes early. Playback was 29 minutes as set. STB Advanced the date for next recording correctly. I went back and reset the time on the correct TP, then took off GMT. Will check tomorrow's recording.
Sunday and today both below 100 degrees inside and out. Insulated shed maxed below 84 degrees. Weather forecast expecting lightning tonight. I had not planned on the a 12 VDC unit recording in this shed, but if this is a heat problem, I will have to run DC power = 100 feet of 10/2. And will be off P* 75E instead of 1 m dish.
I have had many more problems with Hard Drives than with 16GB SansDrive from Costco. I counted (indexing) 103 16GB Thumb Drives. Two Sansdisc failures, would not format, one only recorded 4GB. Eight other brand drives with 4 failures, all formatted, but either failed to record (would not close file / wrong file type) or would not complete or repeat playback.
SO.... still not sure if temperature related, but appears to be recording AND playing back today. I still have not hooked up unit #2. I have had a steep learning slope on this, since I do not have a printer to print the manual, reading the PDF in one building and trying to set up the unit from memory in another has been FUN!!!
The full review will include some of this, but since the object of this unit was to RECORD --- ! And now this looks promising.
