[QUOTE="Andy_2639, post: 1279614, member: 161048"] Thanks for your fast response, CyberSimian Everything on my system is on the same RAID 1 consisting of 2 2.5" 5400 RPM disks. I have a history with Continuity errors ... [URL='https://forum.team-mediaportal.com/threads/recording-and-timeshift-ts-files-saved-by-system-account-with-backgound-priority.136196/']1.15.0 - Recording and timeshift ts files saved by System account with backgound priority | MediaPortal - An Open Source Windows Media Center for FREE! (team-mediaportal.com)[/URL] So I was pretty happy with the behavior a week ago. I configured the TVServer so that the EPG is captured every time I watch/record a channel. I record almost everything, live TV is neglegible for me, so these erros typically are within the 5 minutes pre-recording of the actual stuff. (These continuity errors occur a much shorter time frame than the writing of the EPG to disk takes.)

That is a huge difference. My harddisk changed, now I'm using 2 Western Digital Red 2.5" 5400 RPM PMR (so no shingled, no heat assisted). I'd like to update my system spec but I really cannot find that site ... [ATTACH alt="Capture.PNG"]207215[/ATTACH] That was watching TV with MediaPortal, the 3D graph in the GPU tab of the taskmanager. IIRC the 40% were 720p H264 public broadcasting of Germany which means 10-13 MBit/s while sitting in front of the computer. The 20% were SD content, MPEG2 with I guess Tele5 3 MBit/s ... but via RDP so re-encoding has to be happened. I did another run of LatencyMon. The results were green until I started MediaPortal, then I got a short red spike. I was connected via RDP to the system. I attach the screenshot and log. Changes in the last time: 2020-11-16: I updated the Intel Rapid Storage Technology driver but didn't see any change (but didn't watch TV on the computer since then, just recording). 2020-11-21: Update Windows 10 1909 to 20H2, noticed havy Continuity errors. After that, I updated the Intel HD Graphics driver but then MediaPortal crashed ( [URL='https://forum.team-mediaportal.com/threads/latest-intel-hd4600-drivers-issue.139697']Latest Intel HD4600 Drivers Issue[/URL] ). Downgraded driver to 15.40.42.5063, errors persist. Downgraded the Intel Rapid Storage Technology driver to the version I had before 2020-11-16, errors persist. (At least I hope that there are no remainings of the newer RST software actively running.) More details about the workload of the system: The CPU is throttled to 800 MHz permanently. I have BOINC running with 4 Tasks (= 4 processes with one Thread each) at idle priority. Another process is consuming one logical core at normal priority. Apache Webserver, Ejabberd, hMailServer but with very low load. TVService is running with High priority. MediaPortal client (if running) with higher then normal. Windows 10 1909 had no problems at all with that. Even adding 2 7-Zip threads and parallel recording + watching was no problem. History of Continuity error: At the beginning of my HTPC (end 2015), I had these often - but nor correlated with simultaneously recording + watching. I correlated them more with network or disk IO activity. At that time, I also had a RamDisk for timeshift files. Later, I removed the RamDisk and the situation was much better but not yet resolved. Updating Windows 10 to 1809 (I skip spring feature updates and only take the fall ones every year) was the holy grail: just the few errors after EPG capture - as I just watch once and then throw away the recording, the 0.2 seconds glitch in video/audio don't matter to me. (I think it was with 1809, could also be with 1909 ...) Windows 10 1909 still no problems. Windows 10 20H2: no problems connected with network/disk IO but with watching. Today and yesterday evening I also notices problems when I was logged in to the TVServer computer via RDP but not watching. I also tried PCIe DVB-S2 cards at the time before 1809. The continuity errors were vanished but MediaPortal TVServer did not manage to turn off the LNB supply voltage, resulting in higher power consumption and constantly working multiswitch and LNB. So I gave up that and continued with the PCTV USB card.
