MediaPortal vs Microsoft Security Essentials (1 Viewer)

[RonD]

A few days ago I noticed my MePo 1.5 Win7-64 single seat server/client system started having video stutter problems playing Recorded TV Videos, longer than normal delays (several seconds) when entering TV Recordings, etc. This seemed to happen after the latest Msft "update of the month" and noticed Win7 Resource Monitor started showing MsMpEng.exe (Antimalware Service Executable) using CPU time when MePo Client was active. This system uses Microsoft Security Essentials. I already excluded my MePo recordings and timeshiftbuffer and the system had worked fine for months.

The video stutter would start when I moved the mouse to the top of the screen to show the "topbar" or the bottom of the screen to see the "timeline OSD". Did some poking around.

Disable MSE realtime scan, problem goes away, re-enable, stutter comes back
Exclude all MePo Client data folders, "C:\ProgramData\Team MediaPortal\MediaPortal", problem goes away,
Exclude just the MePo Client log folder, "C:\ProgramData\Team MediaPortal\MediaPortal\log", problem goes away.

I excluded other MePo Client data subfolders and only the "log" folder seems to make a difference. My folder has about 400 files, with 350 MB of files from Oct 2013 when I installed MePo 1.5. The TV Server Log file does not seem to make a difference, started TV Server Config, did a xmltv import to generate server activity and writes to the TVserver log file.

Not sure what changed, but if you use Microsoft Security Essentials or Defender and are seeing video stutter and other problems try excluding the TV Server recordings and timeshiftbuffer folders AND the MePo Client log subfolder from MSE and see if this helps.

Same with me, MP 1.6.
Since yesterday morning everything takes ten times the duration than before, video stutters, changing channels ends up in 30 seconds black screen...

This afternoon I will make the exclusion in MSSE to see what comes out.

Good hint!

Yeah,
same here. I went crazy yesterday night... Will fiddle around with MSE later today. Thanks a lot!

Running MP 1.6 and I've been having the same stutter and slow menu problems as Fafnir and it also only just started
happening yesterday.

I've just disabled MSSE realtime protection and the problems have gone away so it definitely looks like the culprit.

I too was going crazy as nothing ever changes on my HTPC ... just Windows updates .

I've just disabled MSSE realtime protection and the problems have gone away so it definitely looks like the culprit.

Hi kcl314,

In your place I'd just exclude mediaportal.exe and tvservice.exe from the scanning. That worked out feine for me.

Disabling realtime scan reduces your safety...

Ive excluded the mediaportal log folder as per the original post from MSSE and that also works for me.
Yup definitely need to leave the AV on.

When I disable the "MSE exclude Log folder", my problems are not as bad today compared to a few days ago. But I can still see problems when I move mouse to bottom of screen to see the OSD and timeline. Also noticed writes to the MediaPortal.log and evr.log files when moving the mouse. The attached video snapshot F11 shows the onscreen "EVR stats" (press Shift+1 = ! ) when I see frame drops. The 2nd picture is a Resource Monitor snapshot with MsMpEng.exe selected (orange line on CPU graph) when I move mouse and see dropped frames.

Another comment, when I add the MSE log folder exclusion Resource Monitor does not show any significant MsMpEng.exe activity.

The following shows evr.log errors during the dropped frames. It sort of looks like MePo dropped frames and writes evr.log trigger a tug of war between MePo and MSE accessing the MediaPortal.log and evr.log for realtime virus scan and MePo logging errors.

Same here, suddenly went slow and sluggish.

I've just excluded Team Mediaportal from scans in data and prog files.

Also using W8.1 so technically it's Windows Defender (same thing).

OH THANK GOD i found this thread.. Just installed win 8.1 and MP was driving me crazy.. everything took forever, 30-60sec to START mp.. 30+ sec to start a youtube video via online videos etc.. disabled win defender an now everything is smooth as before!

(Running MP 1.7 pre release)

not sure what you tried, but you probably should leave Win Defender real time scanning on and try excluding just the log folder or the main MePo Client data folder.
