    Hello,

    I have ripped some of my Blu-Ray discs using MakeMKV and they seem to have ripped fine with no problems. However, I do have a strange playback problem on my Panasonic GT50.

    Some films exhibit a breaking-up / pixelating of the picture on playback, either through my wired network connection or via the use of a USB stick plugged directly into the TV (picture attached). Strangely, my Panasonic Blu Ray player won't play the files over the network (they appear to be unsupported?) but plays them perfectly with the USB stick plugged into it.

    To sum up, it would appear that the TV itself is having some kind of trouble with random discs (the screenshot is from Django Unchained, but Dredd and Hot Tub Time Machine work perfectly whereas The Other Guys exhibits the same problem)

    Many thanks in advance for any help....

    Anybody experienced this on any other TV? Would moving this post to a different forum help?

    Many thanks......

    Hi, sorry for bumping an old thread.

    I'm having exactly the same problem with my GT50.

    Almost every other MKV has this problem and it always starts occurring at 10 minutes play time.

    I'm using Serviio for streaming but the same thing happens when playing via USB HDD.

    Does anyone have any idea how to fix this?

    Thanks in advance.

    I'd recommend running the "rip" through mediainfo software and attaching/posting what it reports here...

    Between 900MB and 4GB.

    I've re-encoded the same file using HandBrake and this one plays fine.

    All I can spot is the difference in format profile and bitrate...perhaps bitrate is too low and the TV doesn't like it...

    perhaps some tweaking in makeMKV is required to get this right...
