Yeah, honestly thats why the ability to change the associated program is a big deal. I guess there's license issues with the different formats which is why there are no mobile stock video players that just play everything.
But when you can select a 3rd party one thats reliable and does everything, and make it the default associated program for that file extension, it sort of stops mattering. You forget about after an hour or two. It will still be nice when they beef up the stock player, not sure that I would notice or bother with it even then though, mx is just so good, and its what Im used to.
And when they all do, Ill be right there with them, but until then, Flash is sideloaded mate
