Not that I'm aware of and, anyway, BH has usually got built-in the capability to play (almost) every kind of file.
OBH, instead, has a different approach: you have a lighter and essential image and then you add what you need and only if you need. This makes this image lighter than BH.
I have to react to defend my image Black Hole

I do not have the same opinion
smaller use of flash does not mean that the image is lighter and that the responsa is better and greater speed.
On the contrary, I think Black Hole is in favor of that just because of it, less coding and options.
Let's say in Open Black Hole they do not have the py files in python folders they are cleansed
because they are not needed for most users and other things are not in the image.
Options overload coding which of course reflects on speed,
the truth has lately been improved in Obh.
I think Black Hole is the best image for those who use Box for Satellite TV
because it has all or almost everything for that use.
And it's coded just to save the best performance.
On the other side, Open Black Hole supports some things that do not support Black Hole
mostly a multimedia part.
And a great number of options for the user.
Still my point is that Open Black Hole would be far more ideal
without some options that no one uses or can hardly use
because you have to use no practical button actions.
On the other hand, some skin options are not usable except in simple skin
without graphical processing of buttons and backgrounds.
Too many different EPG panels and the like which is unlikely to be used by any or very few users.
So the choice is not easy.
But I wanted to break the belief that the image is lighter and faster because it occupies less flash memory.
So depending on the use
Use Black Hole or Open Black Hole image.
You use SAT use Black Hole if you use multimedia you are better off with Open Black Hole.
