Windows Media Center alternative?

Question

I am looking at an alternative to windows media center for recording and watching TV. Setting up the TV tuner in media center was super easy, but all the other software I've tried was difficult to set up. My video is coming from an S-Video input, and I would want to have a guide. Like in Windows Media Center, I would want to be able to change the channel with an IR remote control. I would want it to be free. If there are multiple steps or programs to install, could I have detailed instructions? Edit: It is ok if it doesn't support an IR remote if that is difficult to find.

Answer 1

Plex, NPVR, and Kodi (with addons) all have Live TV functionality.
