How to set up a fixed resolution?

[Paul]

Glad it's working now, Yama As you say, your TV model will only play video at certain resolutions. The new Thomson TV device profile ensures that streamed videos always have these fixed resolutions. We'll include this fix in the new release, Mezzmo v3.3, that we're just finishing now.

But why it played other video with the same resolution?
This video worked all the time:

OK - I did not know that. That suggests that your TV can play video at different resolutions, but certain videos that don't play may be encoded in such a way that your TV cannot read and play them. How many videos do you have that do not play (using the older Thomson TV device profile)?

[Yama]

The one that didn't worked was the first, maybe one or to more that I don't remember because I didn't wanted to watch them.
I have many other videos with the format 21:9, my tv won't play them without transcoding.
And some strange resolutions like 1920x1040 are sometimes played with transcoding, sometimes not.
So I can't figure out what could that be...
Well... The non-working video is working now with the new profile, didn't tried other videos yet.
Thanks!
