I currently have two HR24s and one R22 and I'll be replacing the R22 and I have Whole Home DVR, DirecTV2PC etc. 1) Is the HR34 worth it? FYI I can get one for $98 installed and I didn't even try to talk them down further. 2) Are there still a lot of bugs? 3) Is it that much slower than the HR24? 4) Can I really go back 5 weeks to watch any episode of any show or if I turn on a show late? (see last two Granted! items in the Compare box at the bottom HERE. 5) Do I need professional installation? Reason being, one DTV rep said yes and one said no and if I don't, I can maybe get an even better deal. Any help or advice will be greatly appreciated.
