I'm finding that constant swapping between progressive and<br>
interlaced very<br>
odd. Do you get those messages on the non-stuttering frontend? Does<br>
the<br>
recording play stutter free on the main frontend if you use another<br>
player<br>
like VLC? What does mediainfo say about the file?<br>
<br>
It is not uncommon for the format to change at commercial breaks<br>
and the<br>
like but the messages above seem to indicate it is changing every few<br>
seconds and sometimes every few frames!<br>

I began writing this email about two hours ago with all of my efforts.<br>
Basically, when I hooked up my FE/BE to my analog KVM and then<br>
directly to<br>
my usual computer monitor, the stuttering went away in all programs I<br>
tried. I was getting stuttering in Kodi, Plex Home Theater, Myth<br>
videos,<br>
I'm sure everywhere else, too.<br>
I finally started looking at settings on the TV. I wound up<br>
changing the<br>
Game Mode setting to On. The TV says there is a reduction in image<br>
quality, but I can't see it. The stuttering seems to have gone<br>
away. I<br>
can't find it now, so I am satisfied.<br>
So if you have a Samsung later model TV and you experience<br>
stuttering, try<br>
setting Game Mode to On.<br>
Should I put this in the wiki somewhere?<br>
Thanks to Mark and Hika for the help!<br>

It sounds logical, gaming needs faster response.<br>
As far as I can think, the only thing that could get changed this way<br>
is your resolution and possibly the refresh rate. I guess it now sends<br>
other edid info to the computer.<br>

In theory it should also eliminate overscan, which is a feature that<br>
belongs in the analog age.<br>
<br>
When your incoming signal is a known 720 or 1280 digital signal, and<br>
the tv is flat-screen digital with individual pixel addressing, why on<br>
Earth did anybody think overscan was a good idea?<br>

On Samsung TVs, setting Game mode eliminates the TV's processing of the<br>
signal--so you get exactly the output that X/MythTV gives without your<br>
TV screwing it up (to "make it better"). The processing goes quite a<br>
bit farther than just overscan, so it's a very noticeable difference.<br>
As a matter of fact, if you're sensitive to sync issues and you're using<br>
something other than the TV speakers for audio output, you may even see<br>
an A/V sync difference because of all the time the TV spends processing<br>
the video before displaying it.</blockquote><div><br></div><div>Today, I addressed this again because of the differences in picture quality with regular mode vs. game mode. I dug up the manual and I looked at the options in Menu -> Picture -> Picture Options.

I am still trying to get the levels that I want, but I initially set MPEG Noise Filter, Digital Clean View and HDMI Black Level to Low and Auto Motion Plus to Smooth. This does show a good improvement over what I was seeing with Game mode enabled. I may not have everything set to the ideal values but I was able to watch some recordings without the speeding up, slowing down and slight stutters I had with the television's default settings.<br><br></div><div>If you have a Samsung TV (mine is from 2014) and you have a similar experience, check out the Picture Options to see if you can fix your issues.<br><br></div><div>Thanks,<br></div><div>Jerry<br></div></div></div></div>
