Currently what I do to watch TV shows/movies is plugging my MacBook Pro to my TV via HDMI. I would like to stream the video from my Mac to the TV via wifi instead, so I'm considering getting the Cromecast or the ATV. Considering I would only use it to do that (display videos -mainly mkv 1080p-), what do you guys think is the best alternative? I'm afraid of getting the ATV and Apple renewing it in 3 months. Also, how would I do it? I've read of people using Chromecast+Plex, or ATV+AirParrot. I've also read that AirPlay does have a little bit of lag. I could really use a little bit of help here. Thank you in advanced!
