Pls help: Why WebTv on Amiko 8300 not working?

[papagal]

Hi there!
Please help: On my Amiko 8300 I have as firmware AMIKO HD-8300 Sw Firmware emu 1.6.65 black synaps.
I can load the prepared WebTv List, but when I click on the names of the channels the channel starts for 1-2 seconds and then the screen turns black + a small message appears "Release Media, please wait" and that is all
Picture remains black.
All the streams are functioning on my PC, but on the Amiko they remain black after 1 second of picture.
My WiFi connection is 100Mbps.
In YouTube section is also NOTHING!
Is it from the firmware?

Here what is in my WebTv List.txt-File for testing:
Channel name:Sport
URL:http://178.219.48.14:8000/sport1
Channel nameФ:УТБОЛ 1 НТВ-ПЛЮС
URL:http://178.219.48.14:8000/ntv-football
Channel name:ФУТБОЛ 2 НТВ-ПЛЮС
URL:http://178.219.48.14:8000/ntv-football2

Is something in this format wrong? Should I change here something?
Just after 1 second the picture disappears.
But as I wrote: All this links/streams work om my PC in the VLC-Player.

Could anyone help, please? Thanks in advance!
