Devices/Software to purchase for the best in Video Streaming

I’d like to expand my system to stream HDTV from my pc to my 65" flat screen but I’m not sure what I need. I have a reasonably fast wireless router (Linksys E3000). I also have - and thought I could use, an LG Network Blu-ray Disk Player but I can’t see my shared folders from the player screen, so maybe not… Disconnected firewall, etc. doesn’t help but even if it did work I don’t know if it’s the right solution. Also thinking about using an NAS (Synology DS111) but hate to randomly buy it without some idea on the benefit.

Any suggestions anyone??
