as always with these chinese noname things it all comes down to firmware support
most of the cpu's have inbuild hardware video acceleration but most of the time its not used because of lacking kernel modules and drivers in android os and no you just can't hack another one....
sometimes the cause is licensing, these devices tend to run android as an vm image and not an actual install which makes it a pain to develop on them. ( you should run the vm ware to test your apps on windows like they are already running on real hardwar like an emulator)
just buy it
run mx video player, if it crashes here you go! left with hope for the modding roms
