Found in multiple mediaportal versions from latest svn from to 0.2.0.0 (stable) Symptom: Every minute Mediaportal.exe uses 90-95% CPU for a period ranging from 17 seconds (fastest system) to 50 seconds (slowest). It does this every minute regardless of other operations. (Ie, Recording single or double tuners, or just sitting idle) Problem verified on three PC's (32bit XP2400, 64bit 3200 and an Intel 2.2ghz celeron, with memory ranging from single 512mb dimm to a system with 2gb, on a variety of hdd's, abit and asus motherboards) I suspect problem may be narrowed down to TV Schedules as on a new install MP behaves normally. It is only when new schedules are imported that this huge CPU demand starts. What is called every minute? Things I've tried with no effect: Turning off "Get EPG via DVB" Removing both TV cards. Multiple reinstalls, always reinstall from scratch after uninstalling. Keeping only 7 days' schedules. Unloading ALL by "My TV" plugins. Ensuring no other programs are running. Also, when running TvGuideScheduler when importing listings, both it and MediaPortal.exe use 100% cpu for a long time (30 minutes or so) AND astounding amounts of memory. I've clocked TVGuideScheduler allocating 1.6GB of RAM (forcing a resize of the pagefile). I have about 20 channels enabled (UK Freeview) with up to 14 days schedules. In MP, TV -> Scheduled programs. If I click "Cleanup" after five minutes of 100% usage, I get the "x schedules removed, OK" button - but MP continues using 100% cpu until forcibly closed (request close is ignored - I've left it working for 2 hours just in case) These problems have been with me since I started using MP some six or so months ago and since I am only using it to record DVB programs, I'm disappointed the demands on the system are so huge. I can understand these things if what it was doing at the time was demanding - like displaying video, but it's just sitting there counting seconds until it's ready to start recording. Please tell me if there is any hope if improvement with this high CPU usage when idle and when importing the tv schedules, and big demands on different systems with little in common with each other apart from the dvb cards.
