You can determine if a video is progressing or interlaced
during <br>
playback by using Menu -> Video - Advanced (I think
that's right). I'd <br>
imagine most sports would be interlaced, and maybe news
reports.<br>

<div>Sadly, there are no Australian channels doing 1080p - the
best they do is 1080i ... which as Stephen mentioned, often
results in judder/jagging for sport or panning type movies
if not dealt with correctly.</div>

<p>In the USA, the OTA ATSC 1.0 is only either 1080i@30hz or
720P@60hz. To my eyes using a PC with something like a Nvidia GT
1030 GFX card I don't see any problems with 1080i which is 1/2 my
channels. I can't tell it from 720p except using data like what
you get with OSD Menu -> Playback -> Playback Data. <br>
</p>
<p>On 1080i, I see FPS= 29.97+/- 0.03. On 720p, I see FPS 59.98+/-
0.05.That's using OpenGL High Quality software.</p>
<p>However, on the Nvidia Shield TV 2017 edition the android
mythtv-frontend shows about the same data but 1080i is +/- 0.07
jumping to 0.12 occasionally. 720p is +/- 0.11 and steady.</p>
<p>I think a lot of this panning problem is due to broadcast
choices. I notice the bits per second on my major networks is
about 3-4 GB per hour, but the sub networks show reruns of the
same shows at 0.8 GB per hour. They also use 480p but the panning
jitter is really bad.</p>
