Perhaps this app needs a system where users can rate if a channel works?
Too rate thumbs down and the channel link is flagged for review by the owner, but then this would need a simple website setup to maintain this system?
I like the idea.
For the uk you can just goto www.tvcatchup.com to watch uk freeview channels.
That is legal and never goes down :)
