The combination of PS3 Media Server and the basic DLNA player on the KDL-46W5100 TV work fine and would make many people happy.
The problem for me is that I am using a bridged wireless-G network connection between the PS3 Media Server and the TV. That’s fine for streaming small DVD-quality divx movies but it’s not fast enough for streaming 720P and (especially) 1080P HD movies. I am usually able to play a couple minutes of a 720P movie before the stuttering starts but there’s no chance of playing a 1080P movie.
So what are my options? I could upgrade my wireless-G network to wireless-N. Certainly, the vendors of wireless-N routers would have you believe that you can stream 1080P movies with no problems over a wireless-N network. If you do a little googling, you’ll find that some users have success and others have mixed results. Anyway, it’s a lot of money to spend on something that is not guaranteed to work perfectly.
Another option would be to run some network cable through the walls to extend the reach of my wired network to the TV. That would certainly work but it could be messy and costly. Luckily, I have a friend who does this sort of this for a living and he is going to run some cable for me in the spring.
Meanwhile, I have gone ahead and purchased a WD TV Live Media Player to play movies on my TV, without having to stream them over my slow wireless-G network. So far, I’m impressed. I’ll post a review here at a later date.
