I got the device on Sat. Overall quite impressed by it. Feels quite a bit more polished than the original WDTV Live I had a while back. No problems with all the contents I throw at it.
I use SageTV DVR software (awesome btw) to record on my PC, and I share the record location so the WDTV can access it and play it back on my 2nd TV. I don't have to wait for the show to finish recording to start watching. If I start watching 5 minutes into the recording, it will continue to play until the show is finished and doesn't end after 5 minutes. Very nice. The total time display only shows 5 minutes, but that's not a big deal..
It's not quite as snappy as the Sage HD300, for which most operations (start movie, 30-second commercial skip, etc) is instantaneous. The WDTV's speed is quite reasonable for normal usage and feels a bit faster than my old WDTV Live. The only minor pain point was commercial skip, I use FF to get the job done, but it would be much better if there's a 30 second skip directly. (The Sage remote have 2 skip buttons, I set one to 30 second, the other to 10 second.. This makes skipping commercial a breeze with its instant response time).
Picture quality is also quite good. When I tested it on my main TV, a 60" Plasma. I almost wanted to say the WDTV has a slight edge over the Sage HD300 when playing back 1080i recordings.
Netflix was good, but not as good as I had hoped.
It always starts out with really crappy picture quality, and gets better pretty fast. How come it doesn't buffer the HD stream from the start? Both my Roku and Sony BX18 bluray player plays the HD stream immediately.
The device does have an option to match the refresh rate of the media. If enabled, I presume it will output 24fps if the media is 24fps. (not sure if this setting will output 24fps on 720p media if resolution is set to 1080p. More testing needed..)
It does not have an option to change the output resolution to match the source content.
Is there a way for me to check what resolution the device is using for HDMI? ie, 720p, 1080p? 8bit, 12bit?
Overall I am quite pleased by it. Nice addition to my setup to enable my 2nd TV to access all the network contents.
