I've had the HR24, I've had the HR34 and now the HR44 and I think the HR44 is a much nicer unit.. Definitely notice a speed difference, noticed that right away. When I had the HR34, I was having problems with freezing issues. I'd be watching TV and it would just freeze for a few seconds, then come right back. Other times it would lock up completely where I had to either turn the channel or reset the receiver. It was still doing this after about 5 tech visits, who pretty much replaced everything, still didn't fix the issue. So, after all of the trouble DIRECTV upgraded me to the HR44 for Free, along with 3 new clients and thus far I haven't experienced the issues that I was having with the HR34. I actually like the remote better, I like the size of the DVR, it's small and I just like how fast it operates. I noticed a difference instantly. I guess the problems worked out for the best, as I got the nicer unit, in my opinion. I will say I'm not crazy about the Clients, I think I'd rather just have individual receivers.
