Bruce, How did the experiment go with the BBB and setup. I am contemplating using the BBB with vdr as a pvr backend. I also want to use something like a Rpi for frontend, I want to watch live tv from hdhomerun dual tuner (i'm in USA) and be able to pause live and skip back. I am not worried about having a lot of storage for recording. if you can share any insights much appreacited, Thanks jv On Thursday, July 25, 2013 9:21:14 PM UTC-5, [email protected] wrote:
