I've been playing with the new leanfront app on my Shield TV on a
4K-60fps Samsung TV. I'm comparing the mythfrontend app to the new
Leanfront mythtv app. If I watch a networked news broadcast which is
1080i OTA recorded from and antenna and a Hauppauge WinTV Quad PCIe
tuner I see only a very slight difference. The news broadcast has a
text crawl along the bottom inserted by the local tv station with
weather and traffic. Depending on the app you view this with, you can
see small differences in the jitter of the news crawl. Normally with the
TV showing the news straight from the antenna using it's internal tuner
the crawl is perfect. With the Shield TV Kodi app, and Mythtv-leanback
app the crawl is perfect just like the TV only viewing. The Shield TV
Mythtv-frontend android app has just a very slight jitter in the crawl.
You have to look hard to notice it. Also testing with the Raspberry Pi
4 with mythtv combo Frontend and backend there is no jitter on the crawl.
So now for a couple of questions on the Leanback app. Is there a way to
delete a program from the list you don't want? How can you skip forward
and backward easily. using the ">>" control seems to be very hard for me.
