## Plugin Issue

- [x] This is a plugin issue and I have read the contribution guidelines.


### Description

Skai plugin is broken since yesterday, but actually it is no longer needed because they provide a lot more stable stream (they don't change stream three or so times a day). **Imho it can be removed.**

New live url as follows:

http://www.skaitv.gr/live
