I take it you have username password URL?
I think nanomid only accepts an m3u URL.
A) You could could ask your provider for a m3u URL
B) work out the URL , from the details you have.
C) use a m3u playlist website / app editor, like IMPlayists . These would generate a m3u URL for you .
The issue with B and C is your provider might not like you doing that and could disable your line
D) use a different app like iboplayer.
E) buy an android device to plug in your TV.
f) I'll stop thinking of ways around it. :-)
