This last one was the final tipping point for me. I've posted a few times about streaming to my home theater from the media on my Mac through my Playstation 3. Well, this TV is also supposed to support the same DLNA client functionality, meaning I could have one less device in the loop. The W5100 also has various network apps provided by Sony, such as some rather useless Yahoo widgets and a variety of streaming audio and video channels.
So far, the streaming audio and video provided by Sony works great. No stuttering with my UVerse 12Mpbs service. The quality is what it is - most video channels look pretty good, except for the YouTube video, which is being blown up a little too much for its own good. The real find for me so far is the support for the Slacker radio service. I was familiar with Pandora, which is a similar service. But while Pandora provides streaming radio "stations" based on your preferences, the Slacker service seems to provide more control over what goes into your custom stations, and also provides a large collection of existing stations. The selection of Rock stations is great, and the audio quality is wonderful. There's also a Slacker app for the iPhone. I'm going to be using this a lot, especially since the URGE music channels provided by UVerse are rather meager in comparison.
However, the current downside is that the DLNA streaming so far is not working. The Bravia reports finding both Mac-based (MediaLink, Rivet) and PC-based (Windows Media Player sharing) servers, but then reports a problem connecting to either of them. I don't know if this is a router issue - maybe the UVerse router is somehow blocking access? Or maybe DLNA is not as "standard" as I think - maybe DLNA for the PS3 is somehow subtly different than DLNA on the Bravia. At any rate, it still needs work.
[Update: I've now gotten WMP to share with the W5100. In WMP, you have to approve each device individually for connection. I thought the TV was on the list, but they were all listed as "Unknown Device", and it turns out the two I had approved were my PS3 and the UVerse set-top box (which also has some media streaming support). Once I approved the Bravia TV, the sharing worked fine. Of course, this doesn't directly help me, since my main goal is to share from my Mac-based iTunes library, not my Windows-based WMP library. But at least it's a step forward.]
Video-wise, I'm mostly satisfied with the W5100. It's my first HDTV, so obviously anything is an improvement over what I had. Considering all of the horror stories out there, I found that this TV actually does a pretty good job with standard-def signals. Ordinary DVDs look great, too, although I don't know if the Playstation 3 upscaling or the Bravia TV processing is responsible. The High-Def looks great, as well - the only problem I've seen is a little bit of fuzz around some players while watching a basketball game, so I'm going to have to keep an eye on the high-speed processing. But TV shows, other sports like football, etc. all look great. No Blu-Ray disks yet, so I can't report on how wonderful they look compared to plain DVDs.
So, finally - I've scrambled up to 2008-level home theater technology! Now where's my hovercar?
