Many of today's BluRay players. But I'm a little fuzzy on the stream source. I know RTP well, but I'm finding folk that are new to this area (and that's OK) but I'm guessing the WD Media Player can offer both files and DLNA (I don't know what DNLP is.)
https://www.google.com/search?hl=en&as_q=dlna is the list I'd go down and see what looks good to do this.
Don't dismiss units that can use the file access method. And don't get too excited about DLNA since it is a very poor solution with many complaints about encoding and issues with fast forward, etc.

I have an LG HDTV that has HDMI input but no ethernet input. The USB input is only able to receive photos and music. I have a Western Digital Media Player that has a hard drive. It can stream HD content from the player over a network that I want to be able to receive on this tv. The player is DNLP compliant.
I need to have a way for the tv to accept and interpret the stream so it can be seen on the tv through the HDMI input. I have a Roku. Roku told me that this device cannot receive a streamed signal. The Roku can attach to the tv through HDMI if there is any way to use that. I called Linksys and they told me that I would need a bridge attached to a media player that would then plug into the tv by HDMI. Is this the only way to do this or is there a simpler, less costly way of doing this?
