Does Netflix broadcast anything in the original format? I finally started a trial this month and have randomly picked a Fawlty Towers episode. The version on Virgin's Tivo is appalling - all the quality of a Real Media clip and with a filmic effect. I bought a Fire stick yesterday as the app is ridiculously slow on Tivo and although navigation is much better the episode on there is juddery and can't seem to decide whether it wants to be filmic or not.
In the end, I got the DVD out
So is something wrong with my TV or is that just how it is? A film I had on last night had the feeling that everything was running a little fast!
Star Trek TNG is in 4:3 when I watched on Amazon Fire TV. Have you changed the settings on your Fire Stick to 1080p/50Hz? Some of the Netflix output is 60Hz, but the British material is still 50Hz. Also change your tv settings to 'Just Scan'
I'd add the Fire TV is a lot more responsive than the Stick.
