Yeah you have a point, I agree.
I use a mixed list of channels and in some boxes it works great but... Be that as it may, we all know that Vu drivers are not all that great at times, sadly...
Let me explain on an example or two, as that is best...
For some boxes PurE2 doesn't come with FFmpeg, Exteplayer3 etc. Coders think it's simply good enough as it is without it,for basic functions. You only get FFMpeg, ServiceApp, Exteplayer3, Media Player2 if you install FNC plugins additionally.
But not all boxes have good enough kernel/drivers, strong HW etc. So, for some we need FFmpeg and Exteplayer3 and in some we do not. At my end, such defaults mostly work well like that. But in some (GB X1) I must use ServiceApp > GST Player and that works fine but internal Gstreamer stuff doesn't work properly. And so on.
So, yeah, if that was an IPTV channel, then yes, sure... ;)
