Hi,
One user reported me about a problem with a playback of MP4 video created in PTE 9 and copied to USB drive connected to his TV.
He can hear a short sound "click" or noise during first 1 second of playback.
I don't observe this problem with my LG TV.
Can you check with your TV, please?
MP4 video, 1920 x 1080, High Quality, 30p.
