I set up the A9F yesterday in a temporary mode for 2 weeks. I am working through the setup issues and fixing them one by one. It is tough for me to use the on line manual, my last two Sony TV's had a paper manual. I finally figured out how to find a USB storage device and reaffirmed the process when using the online troubleshooting manual to research another problem.
I do have a USB question: I downloaded a few Sony demonstration videos on to a USB storage device. When playing the file on the A9F every now and then there is a flicker of the audio and video that is really small. I am using a 3.0 USB thumb drive for the files. Has anyone else encountered the same problem? I am guessing that the file transfer, from the USB thumb drive, cannot keep up with the on board video processor. I am using a San Disc 32gb USB drive.
