I have a bunch of DVDs ripped to my pc for back-up. How could i play them on my TV from the other room?
What would the Wi-Fi be for? Wouldn't an Ethernet port work better ?
Yes Ethernet would work better. I was saying if the modem was far away. Then either Wireless or Powerline would be a good alternative. However both can be problematic.
If you don't know or want to troubleshoot Wi-Fi then stick with Ethernet if you can.
You will need a Blu-Ray player with DLNA like said above or a set-top box or game console.
The Roku DVP doesn't do DLNA right now however does file sharing if you setup a server on your PC. Which sells for as low as $60.
I didn't check the models I posted if they support DLNA. The PS3 is normally $300. However if you look around online you'll find some bundle deals. Bravia internet video is coming soon which is Sonys set of apps for there Blu-Ray players. Skype might be coming? If you plan to play games too. Not a bad investment.
