On the other end of the flexibility + compatibility scale, if all you need is to watch The Wire on your iPhone/iPad/Apple TV v4 on the couch instead of at your computer, I've been using Infuse. Just turn on SMB on your computer and fave a few directories, then stream away. It'll even pull in metadata, cover art, descriptions and sort shows into seasons.

(Arguably, Infuse is very compatible with whatever your video source is, but it only runs on iOS.)
