You need to pay for Android App, you need to pay for plugins, you need to pay for Skins, you need to pay for..... If you got the whole package you need to pay more than 200$. Some skins are at 25 Bucks each, unbelievable...
I've paid for HECO and Eve for MediaPortal/MPExtended and they were not as great and instant working as plex. Connectivity problems, hickups from MPExtended. Endless configuring the right profiles. Deinterlacing problems with TV.
So all lost money.
Plex app works out of the box. Skins and plugins are extra and i only use Plex Media Server as a replacement for MPExtended.
Syncing your movies and tv shows on the background and to lower resolution to iPad/iPhones etc for offline usage is better then using Handbrake all the time for everything.
Photo's do sync too.
I can highly recommend it to other users.
