Just checking, but I have seen no improvements when it comes to the slow response of the DVR related to the playlist. Anybody having better luck? I almost do not like using the DVR as it is so darn slow.

Are you using MRV?

I do have my HR21 networked to be able to download movies (free as I am cheap). Just downloaded directv2pc last night, but the slowness issue was there well before I networked the dvr. Did get a little faster when I hooked it to the router but very quickly turned into a turtle again. I was thinking about hooking a desktop power supply to the external hard drive to make sure it was not a problem with the external enclosure. Why did you ask if I was using MRV?

Lots of reports about networked HRs slowing down awhile ago. Doesn't seem to be as prevalent now, but I'd still consider that.

Why did I ask you about the MRV? Gotta go back and see why. Don't remember...got it, you mentioned the Playlist. I've got kind of a unique setup. Right now I have 11 HRs on MRV, and the Playlist is very slow when I'm using the All mode. Nothing even happens for a while, then the HR I'm using wakes up and catches up. I've gotta keep an eye on the power light and make sure it blinks with each remote command or the thing adds all the clicks at once. When I go to the Local mode, this doesn't happen.

That is happening because the CPU (Processor) is too Slow to handle all of the Requests being thrown at it so it Queues up the Tasks that it can't get to so when you see the Light Blink it is telling you it accepted the Command or Request and has Queued it up but can't react to it until it finishes a labor intensive Task such as Building Your UPL (Unified Playlist).

There are many times when the system is so bogged down that it doesn't even ack the command request (no light blink). At these times (and I've observed them many times on my HR20-700), the system is really compromised, channel entry is impossible, no remote response, etc. Then things get "freed up" and some of the stacked commands get executed in order, and the unack'd commands, are, of course, ignored.

The problem comes and goes, and has for a long time. It's a horsepower problem, to be sure. The alarming part of this is that the HR24's are starting to show some of the same problems. (which, to my mind, was perfectly predictable):)

The reason that the HR24s start to Slow down is the Buildup of Tasks such as the UPL, sorting the Guide, Processing Requests for Series Links, etc. As these tasks increase it severely impacts the CPU which can handle alot more because it is Faster and has more RAM. That is why deleting recordings helps along with rebooting and freeing up temporary storage.

I like (and subscribe to) that theory.:)
