Input:
Question: Will it play video off a networked computer. I have tv shows and movies on my desktop computer I want to play on my tv.
Document: Love these, I own several for each tv and they work great. I can stream from my computer, media server or an external HD. The app is not any good but you really don't need it.
I primarily bought this, so that I could have a better interface to play movies from my 2TB hard drive. It does that, and more. It's small and very easy to setup and use. I love it! The only reason I didn't give it 5 stars, is that when you turn it on, it takes a relatively LONG time to boot up. Other than that, I highly recommend it!
I have this hooked up to my daughters' TV and they're able to watch 1080p movies from an NFS share without a stutter or loss of quality.
I've tried Android PC sticks, a PC I built just as a mediaserver, a Roku 3, and Xbox 360 hooked up via windows media center. All of these were hooked up through my in house network (wired) to my main PC. My PC could play anything, but controlling it was a pain. The Roku couldn't play any of my files so that was quickly given away.
I also had to strip out foreign languages if English wasn't the first channel, because XBox doesn't let you choose which audio to play. This was becoming a pain so I started looking for an alternative and read great reviews of the WD TV Live. I've thrown every file format at it and it streams perfectly. Even 1080p .mkv files with a bitrate of 6 mpbs only takes a second or 2 to start playing. I can now actually use subtitles  and can select which audio channel to use.
I have never seen a warning that this item is used. After receiving the item i realized that it is not in original package and item has scracths on it. So it is obviously used one
This means the WD TV Live has to scan your folders and keep metadata in that folder. The problem is this update process is not automatic (can be set to scan on startup), so if my WD TV Live is on and I download new files I need to manually go to the Media Gallery folder and click options and choose to rescan my files, which can take a few minutes since I have over 960+ files in that folder.
Recommend a XIOS by PIVOS or HTPC as an alternative.Pros:When the unit works, it's great. Plays everything.Cons:The majority of the time it cannot get an IP address, access the internet, or see network shares.This may be due to the faulty network hardware which is available on the forums.Unfortunately I cannot spend any more time buying/replacing units and will switch to a HTPC or XIOS/PIVOS unit.

Answer: Yes.  It plays everything I have tossed at it.  The latest firmware seems to have bugs so you may have to downgrade.  I have 4 of these units and have been very happy with them.
