Per Joel in the other thread, he said he believes it outputs at 50Hz in the UK. Not sure if that was definitive or not.
He said "probably", no problem with an honest guess.
But if i google NowTV and 50Hz, things come up:

The NOW TV Box is based on the Roku device, which is an American product that outputs in NTSC which is 60Hz. In the UK, we use the PAL standard which outputs at 50 Hz. This difference is negligible, especially when watching on more modern TVs over an HDMI connection.

The NowTV box only outputs at 60Hz, meaning anything intended for UK broadcast (eg. NowTV, Sky News, BBC iPlayer and Demand 5 - ie. everything the box comes pre-installed with) does not play back smoothly.
[...] converting 50Hz to display at 60Hz will invariably result in some loss of quality... does! Duplicating frames to get up to the 60Hz results in a 10Hz or 5Hz judder on smooth motion from 50Hz/25Hz source material. I do see exactly this kind of judder on sources like iPlayer - I'm using a PC monitor with the box without any additional processing.
"RaspberryPi forum post" wrote:So theoretically maybe NowTV can run on 50Hz - but it doesn't. And probably won't, if i am guessing right that BSkyB is already doing server-side the 50-to-60Hz pull-down. Also if you have written a channel doing 30fps (or 60fps) animation and player outputs at 50Hz, that may give some eery strobe effects.
It uses the same CPU/GPU as the RPi but the firmware only supports 60Hz field rate. That has two potential drawbacks. [...]
2. Even if your TV is OK with 60 Hz video, much of the content from the NOW TV box was shot at 50 Hz. Motion, especially panning shots and scrolling credits, is not smooth.
"TheEndless" wrote:Depends what you call "support". I said "native support", which would be if player pushes out video over HDMI at 24Hz. Can it decode 1080p24 file - sure. Can it output that video as 1080p24 over HDMI - nobody ever said it can (incl. the two links).
If I'm not mistaken, I believe the MHL version of the streaming stick supports 1080p24 (sources: http://en.wikipedia.org/wiki/Roku_Streaming_Player and http://www.missingremote.com/news/2012- ... d-app-upda).
