Re: Xbox Media Extender on Pal Xbox UK: Jerky playback (not 360)

Starting with the usual disclaimer - the MCX for Xbox 1 kit didn't ship
outside of North America, so any usage in other regions is not supported and
not guaranteed to work (especially if you're using modified Xbox hardware).

That bit aside, it sounds like your Xbox is outputting NTSC (60 Hz), not PAL
(50 Hz). PAL content is 25 frames per second, which doesn't divide cleanly
into 60, resulting in uneven frame duplication, which will cause jerkiness.

The Xbox does output in NTSC when running MCX. It's not only 60Hz but only 480i
lines too versus 575i. The problem is with the TV. Most modern TVs will accept
NTSC signals but obviously the OPs does not.

A DVB-T signal is allready encoded.
