View media from your computer to your PS3

What you need:
Windows (XP-7)
A recent router system
Internet cords
PS3(obviously)
Television
Surround Sound system (optional)

Make sure all your connections are in. You can do this wireless, but the picture will be choppy. If your router is 2 feet away from the PS3 then no problem.
Go into your PS3 settings and enable ATRAC, WMA playback and Media Server connection. Leave the PS3 on.
Go to your computer and go here to download PS3 Media Server.
Once installed, go into Navigation/Share Settings. The default is "all", but if you want to only specify certain folders, click on the "+".

A matter of CPU. If you only have one, only playback files if they are 7-900Mb, anything more and your CPU will be struggling to send the data.
2+ cores and you can playback files as large as 4Gb-20Gb.

The PS3 is compatible with a wide range of files like MKV, AVI, M2TS and WMA.

You can even enjoy your music and edit photos. Turning your gaming system into a media entertainment centre.

I can only speak for WinXP Service Pack 3 and Windows 7 build 7100. For me the program worked flawlessly. Handling full 5.1 Digital surround sound.
The settings were fine on the Media Server, not having to change a thing.
I haven't experienced any trouble with the software and I have been using it for 4 months now.
