UHD channels fails to play

[johnnyzet]

I tried to play some UHD channels via SS-IPTV player but they failed to play. The channels are buffering but that's all, because can't open them. Any chance in the future for UHD support?
PS: The streams are playable in VLC.

The streams are via dreambox

Your TV is HD, why are you expecting it to play UHD???

Because I'm planning to buy a UHD TV and i wanna play UHD channels via internet. If it's possible, of course.
