I used to work for a set top box middleware vendor, and at the time circa 2005-6 we had internal charge amounts of about a few hundred bucks for the mid range PVRs at the time. I just looked at a competitive analysis sheet I still have access to and it look like the total BoM for a modern PVR with all the bells and whistles like voice recognition and 4k is around $400-600 including a cheap AV rated drive to store the video. The lower end ones with cloud PVR look like they're crazy cheap, like a low end cell phone. I wouldn't be surprised if the IP only ones were $50 in Q10000. There's a bunch of implementation notes about fiddly expensive analog calibration for the terrestrial and docsis transceivers, but it looks like the two major ASIC vendors both ship turnkey calibration systems to help reduce manufacturing cost. One of them has a nice menu of prevalidated contract manufacturers that already have production lines ready to go once you sign.
