I have a hdhomerun prime, and am currently using Windows Media Center. I have media center extenders in the garage, and on the outside patio. I’m hoping to replace the extenders with Raspberry Pi based htpc’s in the future.
Hdhomerun has now updated their prime’s to act as DLNA servers. I’ve looked at using XBMC on the Rpi, but until there is a PVR addin with DTCP-IP support, it’s not worth replacing the extenders.
