This is weird. I installed a new 942 on Thursday last week. One of the things I checked that evening was the search function. I even setup a couple of test recordings. All was well.
On Friday, Saturday and Sunday, the Search function wouldn't work. On the result screen that would list the searched shows, the title would show Error on the left and the day's date on the right. Interesting thing to note, the Dish Pass search worked ok.
I tried everything I could think of....run switch check, hard boot the unit, etc.
Search would not work.
Yesterday morning, it worked! I tried it numerous times and it worked fine.
It worked again this morning.
