I've responded to you previously.
Read what I've already suggested in the linked response above. Also, make sure you're wired over Ethernet and not using WiFi. The bandwidth on most of these boxes is limited to 26mbps Wifi, which is not enough for high bandwidth streams with advanced audio.
Outside of that, if it's really only "catchup addons" that are causing problems, they're not supported. Stop reporting it here, and find the developer add-ons forums to reach out to them for help. It's an add-on issue and not a Kodi/LibreELEC issue.
Hi Gltch
Well first many thanks for your help and indeed your initial response which somehow I seem to have missed or overlooked. Sorry about that, clearly a senior moment in my old age. I must have appeared rude in not replying to you with a thank you so sincere apologies for that.
Anyway firstly I had not installed more and more add-ons as from the beginning with LibreElec 7 I just used my basic suite of add-ons that I have developed and edited over the years removing dead add-ons and adding new ones that I feel are good enough keeping the total add-on count to a reasonable level. I did not though restore a back up from my S805 Ember based box either but freshly installed the Repositories and add-ons to avoid any incompatibility issues. So the add-ons were not the problem and of course I did a check for background resource hogging add-ons and settings too. Indeed I have an almost identical suite of add-ons and settings as I have on my S805 MXQ M12 box running registered Linux EmbER 4 firmware, and for which I have no such problem with this delay in regaining remote access when running up a video stream.
Although junior on this forum and recent to LibreElec firmware I have been a KODI power user going all the way back to XBMC 11, and prevalent on other KODI forums for some time helping many new comers into the world of KODI and Linux firmware, so I am pretty familiar with the way it operates but always much still to learn. However so far, by either luck or judgement, I have never had the need to obtain and upload a logfile and thus why I was unsure of this operation and the need or value for it with my particular current problem.
Well the network cache settings were indeed it seems the problem, so you have hit the nail firmly on the head. I was simply using the default network cache settings as installed with the LibreElec V7.0.3.012h and earlier firmware and with the correct S905X 1GB Device Tree. I took your suggestions and here below is the Advancedsettings.xml file I have used. This has virtually totally removed the problem with only at most so far 2 or 3 seconds delay, and now often no apparent delay, in regaining remote access and this is perfectly acceptable for anyone of course. I cannot thank you enough for your great help here "glitch" and the excellent informative links related to this issue that you pointed me to. Early days yet but appears to have cured this problem, or at least has sufficiently eliminated it to be no longer considered a problem.

Yes understand the forum rules so only mention catchup add-ons and not by name of course. The problem by the way was also prevalent with pucker KODI add-ons like YT with video streaming and indeed even playing local video files sreamed from my local NAS drives. But this was not an add-on specific problem as it turns out, and was indeed present to differing extents on all video add-ons I used.
I was unaware that these boxes are restricted to only giving about 26 Mbps on Wireless connections which is odd as they supposed to be able to use 802.11n WiFi at 150 Mbps at least, and these days most of our WiFiAPs support 802.11n of course. Normally with 802.11g after security encryption you only in theory get about 35 Mbps max to share between all other active WiFi clients from the specified 54 Mbps, so I can accept how a standard g WiFI connection can end up only giving you 26 Mbps. However in my case I use an Ethernet connection via a hard wired gigabit switch from my 200Mbps internet fibre optic downlink coming via my router with gigabit Ethernet ports too.
Once again many thanks to you glitch for your invaluable help.
Cheers
