I am experiencing the sluggish performance from my HR22 as are so many others. Navigating the guide, changing channels, accessing menus etc. It seems like it functions better when the playlist is shorter with less recorded material and more available space. Has anyone had the experience of adding an external high-capacity SATA drive (ie. 750gb to 1T) and finding that this improves speed?
If yes, what drive did you use? Size? Happy with it?
If you added a large drive but saw no speed improvement please tell me that as well.
There have been a few people who claim that having a DVR with the hard drive nearly full (85%+) will slow it down a bit. I've never noticed it myself. Assuming it is true then adding more hard drive space should make it easier to keep away from being full.
I personally am more of the opinion that it is the guide data that is slowing things down. So having a bigger hard drive means you have the same if not more recorded material with guide data that the DVR needs to keep track of. The more guide data, the slower the DVR.
That said, I think there is a new firmware update rolling out now that is suppsoed to help with the speed quite a bit. I have been too busy at work to read about it much yet, but I suggest you check out DBSTalk.com. It's AVSForum's sister site that covers pretty much anything you want to know about satellite TV.
When you say "guide data" are you referring to upcoming program guide data, or data from the already recorded programs?
The general thinking with this is:
Guide data comes in,
Next is sorting through the series links and recordings present, along with the history of the last four weeks.
Then new recordings are scheduled.
"In theory" the more SLs & recordings, the more CPU power is used to sort through this.
Yes, like VOS said the guide data I am talking about is all the data the DVRs have about the shows. This includes all the data for the shows coming on in the next two weeks. All of the shows you have recorded on your DVR currently, all the shows you have recorded and deleted in the last 30 days, and I believe some guide data on the VOD programming available to you if your box is hooked up to the internet.
Your DVR is constantly going over all that guide data searching for upcoming shows it is supposed to record and comparing it to shows you have already recorded and deleted within the last 30 days (it won't record the same episode of a show twice within 30 days even with repeats turned on).
The bigger the hard drive you have in the DVR the more shows/movies you can record. The more you record the more guide data the DVR has to sift through.
As far as speeding it up it seems like you hadn't heard about clearing the NVRAM like ncted posted. While not in DirecTVs manuals it is pretty well known in the forums and you should have been able to find that info here and on DBSTalk pretty easily.
But since you hadn't here are a couple more tricks you might want to try if you haven't.
In your guide options turn scrolling effects off. This tends to speed up the guide and DVR playlist.
In your HDTV settings turn native off and deselect all resolutions except 720p or 1080i (depending on what kind of TV you have). This will usually speed up channel changes a decent amount, but you may notice a slight degredation in picture quality on some channels if you TV has a better upscaler than the DVR.
