A Western Digital Live media player would be one piece to the puzzle. It would work provided you set up your system to use it. I use a WD Live in my entertainment system.
The WD Live works by accessing your media over your home network (LAN), it can connect to your router wirelessly, but for video files it is better to use a wired Ethernet connection. But it will work either way.
Once connected to the network the WD Live will be able to access and play any file on any device that is also connected to the network. This includes PCs, Network Attached Storage (NAS), and any hard drives connected to the router (some routers, but not all, have USB ports). The WD Live has USB ports also. This is why I asked if these hard drives are external drives.
None of this changes any of the advice given to you regarding the hard drive formatting. Jimbo45 has given some excellent options also. Formatting the drives GPT is an excellent choice. That will give you the Advanced Format which is best for video files.
Whether the WD LIve will recognize a GPT disk if it were plugged into it's USB port is not known to me. That piece of the puzzle will require some research (if that is what you want to do).
But if the GPT external drives are plugged into a PC that is on the same network as the WD Live then it will work fine.
