what is the model u have?
it may still be able to do all that!
the requirement for what u r looking for is not so much about the box but the apps.
becos these apps are usually small in size and work on multiple android versions.
of late, vod china drama are getting harder to get due to geoblocks and authorities shutting down the providers.
still, can get them with the right apps, just need to follow closely the updates, new versions, mirror apps, etc.
live tv - easier, several i can think of.
the key is to be able to find those apps at current versions.
u can either find them yrself or buy a box with the seller installing the good stuff u want.
My old tv box has damaged and can't be repaired . Sparks came out .... yes I wonder which lowyat or any vendor can help install those apps
