XBMC DVR Build Advice

Hi All,

I’ve been a long time lurker and since the release of October’s update that includes the PVR/DVR functionality I have decided to take the plunge to build my first XBMC and would like advice on the hardware. This box will mainly be used to watch and record live TV from an OTA antenna, since I have a NAS I wouldn't need a lot of storage inside the box.

Requirements:
• Supper Low power consumption since this box will be on 24x7
• As quiet as possible
• DVR/PVR
• Bitstream DOLBY TRUE-HD & DTS-HD MASTER audio
• Stream 1080p files from NAS – 2D Only
• Bitstream hi-rez audio files (192kHz) from NAS
• Stream 1080P Hulu content
• Stream 1080P Netflix movies

DVR – I’m debating on HDHomerun (out of box) vs Hauppauge (in box) solutions. Any thoughts on each?

Any advice is appreciated, thank you in advance!
