+1 here too. HR23-700
The worst is this:
Type in channel 2-2-9-enter.
Then, it is so sluggish, it changes to channel 2, then channel 2 again, and then to channel 9. Not fun.
After following this thread for several days and trying to correlate what people are saying with what I see happening with my DVRs, I think that there are actually a few different issues that people are talking about. Perhaps, they are related. Perhaps, not. I really don't know.
First, there is the issue of the long delay that seems to come with the first channel change after the DVR has been powered up. That is the delay that can last for up to 30 seconds. For my DVRs, this behavior started after the last software update. Perhaps, that is coincidence. I have no idea whether or not that is the case.
After that first channel change following powering up the DVR, many further channel changes will happen in a normal amount of time, but there are occasional further channel changes that can take from about 6 to 12 seconds. These seem to happen randomly. Again, I have no idea whether these random shorter delays are related to the especially long delay with the first channel change after powering up. Like with the first change delay, these random later delays started on my DVRs after the last software update.
Then, there is also the issue explained in the post that I quoted above. With this issue, entering a channel, such as the 2-4-5, might result in the tuner only recognizing the 2 and tuning to channel 2. Then, a few seconds later, it might try to tune to channel 4 or to channel 45. This behavior seems to occur randomly, and it might last for a few minutes. I doubt that this issue is related to the first 2 because I've seen this issue randomly appearing for over a year.
In the case of my DVRs, at least, doing things like rebooting and clearing out the VRAM may have led to some marginal improvement with the overall sluggishness of response performance, but nothing that I've tried has changed in any way that long first channel change delay.
