Openelec xbmc with Central mediaserver

Hi,

I plan to have a central Windows MediaServer with TV cards running ForTheRecord. It also contains the HDDs with all my music and movies.

As thin clients I plan to use RasperryPi with openelec.

- can anyone recommend a decent media server software for Windows that will best serve the openelec clients?
- maybe a software that can also scan ForTheRecord's 4tr metadata files or where I can easily write a custom scanner plugin?
- will the xbmc plugin also allow playing the PVR contents via DLNA or will it need file share access?


Thanks!
