MKV video plays with artifacts on TV

[mateus560276]

First, I am new here and I am not sure if this is the right section for my question. I apologize if I'm not posting right.
So I've got 7 .ts files, that I joined using TSSplitter, because tsMuxer gave me errors. The result is a single .ts file, which I demuxed using tsMuxer (without errors). I got one .h264 file, two .wav and one .ac3. I made one .mkv file from these with mkvmerge, adding some subtitles. This file plays fine on my PC. However, on a Panasonic TX-P50VT30 E, the video did not play. I played with the mkvmerge settings, especially "Disable header removal compression", both checked and unchecked. Strangely, both files played, but when playing it shows horrible artifacts, and slow frame rate. The original files are from an uncompressed blu-ray. However, other videos (also uncompressed blu-rays) play fine. I thought it may be the high bit rate. The joined .ts files has a data rate of 32578kbps and total bitrate is 32962kbps, as indicated by Windows Explorer. I use a Seagate 1TB External HDD which I plug into the TV. All the videos play perfectly on the PC, but it is powerful. Maybe the TV can't handle the file?
This is some additional info from MediaInfo:

The other video that I have on my HDD has a 25.7 Mbps overall bit rate, which is not that far from 30.8 Mbps for the problematic video. Any help will be appreciated.

Do yourself a favor and buy some media player http://www.iboum.com/net-media-players.php , I thing it is not offensive in your case because that TV costs a lot, so this will not be a $$$ issue. By this you can make this TV a "hub" , device that pulls on screen anything sitting on LAN at your house as well.

Big guys out there have different priorities then try to tune up their playback for mp4's, mkv's , you know what people like .

[aedipuss]

first i'd try remuxing the mkv with a more recent version of mkvtools. it's up over v5 now. open with mkvmergegui and select the parts to keep and give it a new name/destination (i'd also dump the 2 extra audio tracks ). if that doesn't help, the peak bitrate may exceed what the tv can handle from a file. then you might benefit from re-encoding it with something like multiavchd.

also you might find makemkv helpful in creating mkvs from blu-rays. it's free while in beta for now.

[edit] forgot to welcome you to the forum!

Rerip from your original blu-ray that you own. If not then buy it first.

Thanks you all for the suggestions.
@aedipuss
I will try to do what you say. I used the newest version of MKVtoolnix when I saw it. However, I had problems with that "header removal compression" and after searching I discovered that older versions didn't have that problem. Anyway, all the files resulted from mkvmerge played perfectly on my PC so I thought that is not the problem. I see that mkvtools is an OS X application, that is not a problem but my PC is faster and I tried to do everything there. Makemkv looks nice. I will try it when I have time.
@Baldrick
Thanks for your post, although it's not very useful since the ripped files are fine.

I didn't really understand all the things you've written. I am trying to keep everything as simple as possible. If that is the only solution, I will consider buying a media player.
