I thought I would chime in to share my wealth? of experience on Media Center in a networked home. I have tested darn near every product out there looking for something better and so far there is nothing. Not that Media Center doesn’t have its own warts. The lack of a relational database structure being the major problem
I have multiple computers in the home, each driven by a touchscreen. JRiver is not all that touchscreen friendly, especially the theater view, but is it manageable. It would be nice if you could increase the size of certain features selectively. When you increase the base font, the whole top of the form gets scrunched.
Each computer is part of a domain running off Server 2003. This isn’t really necessary but as I develop SQL Server and Access databases for a living, I can double up its duty. The server has 2 Terabytes of storage, 250G wav files (I don’t use compression), 1TB DVD files, 250G jpg and tiff. I have an additional 2Terabytes on another machine which is networked
For general video and audio playback, a Pentium II 400 with 768Meg is adequate. Ram is more of a concern in that a Pentium III 950 with 512MEG doesn’t work as well as the Pentium II. I use these as base systems throughout the house because they are cheap and silent (no CPU fans). Each has a fanless video card with 128 to 256MEG RAM. This is important to play the videos with these processors. I used to keep the library on the server and share this among the systems. This doesn’t work. One is that since it is not a real database share, the last computer shut down replaces the file. Also on the smaller processors, they have difficulty bringing the large library data across the LAN. They work better when the library is local. I do all my updating and adding of media on my workstation. I then backup the library to the server. For each of the home systems, I use restore to update them to the master.
I don’t have much experience with MC12 in that the smaller processors choke trying to run it. Also it doesn’t handle dual monitors correctly. My media room runs dual monitors, one being a touchscreen for control and general audio, the TV being a HDTV that works off of a DVI to HDMI cable. When I tried MC12, it would crash too often.
So regarding your NAS, as long as you put the library local on each machine, it should work fine. All my files are mapped to the server the same (audio, cover art, DVD, photos) so the library pointers are identical.
Hope this helps
