That is what I have tested before requesting this feature, already
For example - to the files that have the name "ABC.mpo" i have added the extension ".jpg" to get "ABC.mpo.jpg".
With this extension - the files were listed and I could access with on my Samsung TV in 3D without a problem (the TV detected the 3D function with this files automatically).
The fact that the Samsung TV recognized the file as a 3D file is very interesting. Could it be that the TV took a hint from the ".mpo.jpg" extension, or does renaming "ABC.mpo" to "ABC.jpg" also lead to automatic 3D detection?
What about Samsung BD-players? Do they also recognize streamed 3D content automatically?
PS: I understand that release 1.40 now makes renaming of these files unnecessary.
I am asking anyway because I am more interested on which Samsung devices and under what circumstances the "renaming hack" works.
