Feel free to tell us about your DLNA and NAS setup. I find that the Synology Diskstation (I have DS213j) easy to use and provide both NAS and media server capability. It is also configured as RAID1 for fault tolerant using dual 4G drives.
For those of you who are not familiar with how it works, instead of going into the technical details, this is what it will provide:
1. A file server on your home network (i.e. NAS) where you can store all your files. Note that fault tolerant is not the same as back up. Fault tolerant ensures that you never lose your data, even between backups. But only proper backups can create historical versions of your files. I have my photo, video and music files all stored on DS213J. Since these are data that I don't need to back up, the fault tolerant feature provides enough protection.
For my most precious data, I also copy them to iCloud.
2. Synology provides a lot of tools for playing music and videos remotely on your mobile devices. It also does transcoding - meaning it will convert the video format on the fly to your mobile device. So I can watch any of the movies from my iPad using the DS Video app. The recent firmware upgrade is wonderful, the video server pull album art and movie rating from online database, very cool.
WR-100 and NuPrime app
The app can detect DLNA servers on the network (in addition to online services and local music on the phone). To stream music to multiple rooms or to any room, I will have to use WR-100.
HD-AVP (I use HD-AVA since I don't have other amps)
HD-AVA is connected to my NuForce S-9 speakers so when I want to enjoy living room system, the HD-AVA can access the movies and musics from Synology server. A WR-100 is connected to it for streaming of Spotify music. Apple music gets stream through AirPlay on HD-AVA.
What I can try next is to setup Plex (another media server) on Raspberry Pi (that $39 linux computer). See another topic about this.
