MKV with format 4:3 and force to 16:9

[klode]

Hi,
I have a MKV movie with the dimension 960x794, and I want to set it up with an aspect ratio of 2.35 - The MKV Merge can do this, but when I say the MKV in my LG BD590 I see it in 4:3

If I make the MKV with AVI Demux, I can force the aspect ratio to 2.35 and the video is fine.

This is the mediainfo report:

How can I force the aspect ratio to 2:35 correctly?

Are you reconverting with avidemux? To a 2.35 resolution size?

I guess the LG wont read the aspect ratio correctly.
