Some MKV don't play on KDL-40W2000

Hello everyone.
I've finished recompiling ffmpeg on my QNAP box in the hope that it'd fix the playback of the mkv that didn't work before, but sadly it didn't.
My TV is the model in the title, it's connected via a PS3 to a serviio 1.4 server running on my qnap x86 box. The renderer profile is set to ps3 in serviio.
Sadly when I play some mkv, this is what I see (this is the Universal logo):


Can anyone help me to understand how to fix this?
Cheers,
Roby

The older TVs (including up to 2009 models) cannot decode H.264 unless the resolutions are standardized (e.g. 1920x1080). Most movie rips have been cropped to remove the black bars, so their resolutions are considered non-compliant by the older decoders (1920x800 for instance). I had asked Zip if he could implement some kind of resolution filtering to the device profile but this he has focused on other areas, I guess because these devices are now so old it's arguably not worth pursuing:

First of all thank you so much for the explanation, I love to learn new things!!
May I bother you with two more questions?
The first would be, if I use a software like VirtualDub or something alike and re-encode the video with the non compliant resolution to a compliant one, do you think that it will show regularly?
The second one is a bit shameful, but oh well... I thought that the TV was only a "stupid" display, I mean, that the whole encoding/decoding was done elsewhere. I thought so because 1) I didn't think the TV, at least this old model, woud have a cpu in it powerful enough to decode such streams, 2) since the TV doesn't connect to the internet, codecs support would start falling behind pretty soon, so in a handful of years it'd not be able to decode anything encoded with new codecs. In my idea of how the whole thing works, someone encodes a video to compress it and shares the file, I download the file taking advantage of the smaller file size, I play it via the media server, so the smaller file size comes in handy when the Qnap box sends its bits to the PS3 via my wlan. Once the data reaches the PS3 media player, that is where the decoding would take place, taking advantage of the powerful ps3 hardware (surely more than the tv at least), its ability to use the internet to update itself, and the decoded frames would be sent via the hdmi cable to the TV to simply raster them...

Did I say something so stupid? I guess I did ehehe

Thank you again!!
