My advice,
DON'T BUY! I currently have one (MED500x2) which I bought at rAge 2011. Sure, it plays most video files without a hitch, but the interface is buggy as hell. As others pointed out earlier in the thread, they always promise to fix issues in updates, but they either never get around to it, or they introduce more bugs! At this exact moment, I'm trying to recover data from my 2TB drive which the Mede8er corrupted. I read about other peoples' hard drive corruption experiences on the forum before and silently prayed that it would never happen to me...

. I even avoided upgrading to those "dangerous" firmware versions.
To summarise:
- Pricy
- Slow network (max 8Mbit/s over Gigabit LAN)
- Lots of bugs
- Chance of corrupting your HD (if used internally)
- Support seems awesome initially, but mostly just promises
- Meta data not automatically downloaded - long manual process (with more buggy software)
My next media center is a HTPC with XBMC. For now, I'll stream my videos over the network - not putting a HD in the Mede8er again!
