The text file only has the firmware number...but it's needed for the update. When I updated to 13.05, I didn't put the text file on my thumb drive, and it didn't work. Someone here(Howl-?) told me to include it, and it worked fine.
Also, I posted in the bug thread, but wanted to post here as well. I downloaded the 13.06 update tonight. Initial reports are that it has fixed the issues. I had minor problems compared to some, but they were noticeable. I see nothing now.
I do have one question...and I know it's early, but what do people thing the Sharpness setting should be on these sets going forward? Still zero? I'm experimenting now.
