Update, some channels stream after a bit of a pause (buffering)
Some channels won't stream.
I think it's this particular model, must have a slow processor or something.
Tried two different high end receivers and both IPTV apps.
Tried both formats for Channel list MU3 and .Txt
So my conclusion is to carry on using my receiver as it's all to painfully slow.
On my LG TV it works great so the Samsung doesn't like this job. [emoji6]
I wouldn't mind but it's only 9 Channels I'm trying to stream, save me having a receiver in my kitchen [emoji23]
