I'll have to disagree with you on the HR34. I'm glad they replaced one of my HR22 that had real issues (Hard drive failing) with the HR34, in exchange for a 2 year commitment. Is it perfect yet, no. But the glitches I'm experiencing since the release of the HD GUI are minor. Like pressing the down arrow twice to activate double play and occasionally ithe screen goes blank and takes 5 seconds to switch tuners. And the progress bar is back to the larger black bar that blocks too much of the screen. I'm not missing any recordings or having any major performance issues.
The HR24 is way ahead of the HR34 in the software development cycle. There are several major software issues with the HR34. A lot of the refinement on the new GUI is implemented in the HR24, while the HR34 is still on its first incarnation. It will be months (my estimate) before its caught up to where the HR24 is now, and hopefully, dependable enough not to require a second DVR to back up recording "must watch" shows, or baby-sitting the ToDo List.
And the bonus is having 5 tuners that can record any 5 channels at the same time. And when I have 3 or more things to record at the same time, no more trying to figure out which DVR to record what show. No more turning on my DVR to watch a live sporting event and finding that both tuners are busy recording something else. Now 3 programs can be recording and I can watch and buffer 2 live sporting events and even monitor one in PIP. Life is good!
