I tested playing some mpeg movies on TV.
As a result, playback was possible. but they have problem.
My all videos give an error message before displaying media list.
In the details of error is displayed "Using formatted text and manually setting a font can cause unexpected results!", so that playing movies that have not been officially finalized may not be considered.
Still, press to

ignore error message, can be display the media list. and select the mpeg movie playback itself was possible.
If video codec matches, seems to be no problem displaying the video.
but they are no sound played. I don't know if this wrong audio codec or players specifications.
This is my guess, although sound is not output, but possibility that software is playing.
Also, TV seems that built in software called "SCEA movie player" is used, this player does not correctly recognize as if mpeg movie title contains lowercase letters.
even If playable mpeg, will freeze with different error message if mix lowercase letters in either extension or title.
Besides, if be large size mpeg video that named correct title w/ extension in the MEDIA folder, freeze when select the TV before get error message.
another case videos above certain resolution, thumbnail in media list correctly show moving preview, but will freeze when selected.
case of mpeg movie whose codec dose not match, can select thumbnail but they have a lot of noise or in the worse case will be freeze.
Currently, seems only BIK movies may play properly and stably on TV in the room.
As side note, if change extension of unsupported movies to BIK, it will be replaced w/ dedicated image.
it somehow remind me of a color test pattern on analog TV broadcasting
