Ok, I founds some tips. I'll give them a try.
Large ext hd nearly full can cause delays some times. Deleted recordings to 39% available
This seems to have cured my problem...
"Seems" is the operative term. How in any possible world can content stored on your HDD that you are not currently recording nor playing back have any bearing on this? The metadata for each recording is indexed so that the play list will be able to appear, but there is no interaction between the DVR and content on your HDD unless it is content you are actually reading from or writing to the HDD at that moment. All other content is out of play. IOW, your DVR has no earthly idea how full your HDD is other than what it knows to display the play list, and it also does not care, until it gets so full that space is unavailable.
I have run HDDs completely full numerous times without ever experiencing any sort of slowdown. Many people never delete anything and allow the HDD to do it (by not choosing KUID) meaning once full, the HDD is always full.
It seems that you have a perfectly-good premise, which is that when there are banner ads in the guide, performance suffers. I think we all agree that this can happen. How that could relate to how full your HDD might be is baffling at best.
My best guess is that on originally-designed SD boxes with retro-fitted HD graphics and unexpected crap-app bloatware, that there is not enough RAM nor virtual memory capability to prevent slowdowns when the box gets busy. If you display a guide page with a banner ad, the DVR has to serve that on the fly with top priority, and other high-priority tasks like responding to remote clicks suffers. That is just a guess, but at least it has a credible theory to support it.
