[QUOTE="craigparris1, post: 387276, member: 75254"] Hi jameson_uk, Good luck on getting to the bottom of this one, because it certainly seems to be something that plagues a lot of MP users, with no particular resolution that seems to suit everybody. I'm not sure how much help I'll be, but I'll tell you my scenario. Like you, I had problems with the PC resuming from standby, and varying degrees of response from the MediaPortal client. I never actually had any problems with the machine going INTO standby - the TV-Server always took care of this just fine. Like you, I also tried a number of suggested fixes throughout the site such as the S3Hack and also various standby-related tools (like MCE Standby Tool and MP StandbyHandler) - without much success. You can read a thread that I created about my problems [URL="https://forum.team-mediaportal.com/general-support-51/mediaportal-another-resume-standby-s3-problem-53435/"]here[/URL]. Again, like you, I also wrote my own little app so that I could try and figure out what was happening. The key for me seems to come down to the resume process, and whatever it is that's happening within Windows at the time. Setting MP aside for the moment, with the small .Net app that I wrote I am logging an entry in the event log each time the PC goes into standby or resumes from standby (I'm just using SystemEvents.PowerModeChanged to trap the standby/resume). I always get an event recorded for when the PC goes INTO standby, but sometimes I won't get an event logged when the PC resumes ..... note: I NEVER get an event logged when the system wakes up automatically (ie. for EPG grabbing or scheduled recording), and I occasionally (but not very often) don't get an event logged when the system is woken up manually (ie. turned on by the power switch). So, given that this is just a small app that's relying on the OS (in my case, Windows XP) triggering a power event, there's obviously something not getting notified properly within the OS. Having said that, though, at the times when I don't get a "resume" event logged by my little app, there are entries in the TV-Server log to indicate that it knows the PC is resuming from standby. But, there can be unusual entries in the MediaPortal client log that seem to indicate that it's not been notified correctly of the original standby or the resume. So, where to from here for me? Well, I guess my next task is to do some research into XP, .Net and power events and see if I can narrow down why the OS doesn't seem to be notifying correctly sometimes on resume. In the interim, I've written my own little hack into my app that relies on file creation and deletion to work out of the system has come out of a resume - then I can restart the MP client properly each time it resumes. Like I said at the top of this reply - good luck getting to the bottom of it. If you can narrow it down to a replicable bug, and get a developer to fix it, you'll have a lot of happy MP users!
