For reasons stated earlier there can be issues watching these streams directly on smart tvs.
The Morton stream was jumpy on my smart tv, but on my laptop it (the stream picture quality) was good.
You should try watching it on a computer, laptop or tablet. Do you have any of those?
Once it is running on one of those devices it should be possible to connect them to the tv which is not the same as watching directly on your tv.
Hope that makes sense!
