WD TV Live Hub (1TB)

Pros: Can play most audio and video file formats

Cons: A lack of detailed documentation and a confusing interface, compounded by software bugs, makes this unit basically unusable for me. Examples, files don't show up on system and I have yet to get file sharing to work with Windows 7.

Summary: This unit offers a lot, but without detailed documentation it is very difficult to configure and use, you will rely a lot on online support forums, where the data is often unreliable.
I have not been able to get file sharing to work with Windows 7, and syncing is somewhat of a mystery. I moved to the WD from an Apple TV which had a very simple, easy to use interface, but the WD suffers from usability issues. I used the Apple TV all of the time (despite it's limitations) but find that I just don't use the WD ... every time I do there seems to be a new issue to debug.
The interface to scroll through music is pathetically slow, and the Media Library is nowhere near as useful as it sounds.
There are so many quirks that you will find, you cannot setup a photo screensaver from a hierarchical folder system, the screensaver picks up all the album artwork as photos, not all the menu options from DVDs are available.
I have a solid background in home theater and computing, anyone who doesn't should absolutely avoid this unit.
