I am trying to build a DVR, but I don't understand what hardware I would need to record both OTA and digital streams. I've decided to ditch cable, but the guides I've read don't explain well to a novice and I am unsure what to purchase. Ideally, I would be able to record off services like youtube.tv or sling.tv as well as whatever my antenna grabs. Right now I have a PC capable of handling the load, a mohu antenna, and the plex pass. Thank you!
Sling has a cloud DVR as part of their service.
But streamed shows are copy protected so you generally can't local record them. Being able to locally record a streamed show could allow you to provide it to others also.
