Between the HDHR3CC and the HDPVR, Ill have the HDHR3CC any day! Setup 1 device and have 3 working tuners. Don't have the (3) STB to deal with. Only get charged $2.50 for single CC vs $30 for 3 HD STB.
The bad part, yes the cable co can change the copy flag as will and without reason (except local/must carry channels). The only channels I have had any issues with have been NBC Universal channels (USA, SYFY, MSNBC, CNBC and some others), which are now copy never on Suddenlink (thanx NBC. All because of the Olympics)...
