Hi, and well, as the questions says, Ive seen the Pæex ramdomly jumps amrew minuts forwared from time to time. This might happen 2 to 4 timews during a movie… Im not seeinh this on my Chromecasts
Any one else experienced this?

How much time does it skip and is anyone touch the controller?
The reason I ask is the d-pad has been mapped to skip forward backward in increments so if the controller is getting bumped in the wrong way it may be a possibility (I normally bump the triggers, but could see how the others could also be getting hit)
I think its just a few minutes, one or two presses on the dpad returns the movie to where it jumped from…
I dont think that its do to bumping the controller, Its usually switched off… Im using either Logitech Harmony remote or the Android Smartglass app…
It seems to me that the server skips one of the transcoded segments…

Interesting, if you could a log (Plex Media Server.log) from the next time this happens (or the last time it happened if you still have one) would be great to pass onto the developers to try and figure out what is happening exactly.
I too have started having this issue starting last week or so. It will randomly skip forward about 5-10 seconds. I have several other plex devices (nuc, raspberry pi, chromecast) that don’t have any issues. Attached is my latest log file.
I’m having a possibly-related issue with high levels of disk IO. I will try using a faster disk on Monday.

There are a number of these entries when you try and play which is typically indicating that the drive housing your transcoder tmp directory is full. (Honestly, I wouldn’t expect this to cause skipping ahead but you never know)
The log is also missing what codecs the file has before transcoding, so I am not entirely sure why it is trying to transcode. All I can see for sure is that the file is a mkv with 15Mbps bitrate (Neither of those two things should force a transcode unless you have turned off direct play or lowered the quality for the video)

I’m guessing the transcode was happening due to the 7.1 audio and only 5.1 available for Xbox output? All settings were on original picture quality. I did discover that the root partition was out of space…will expand that out as well.
I’m happy to report that after upgrading the hard drive for more IOPS and adding disk space, I no longer have any issues to report with skipping. 
i’ve finally had some time to do some testing too. And it does indeed seem to be relatede with HDD going full doing at full/partial transcoding. Especially large movie files where only sound is transcodes from DTS to DD (do to lacking support on XBO). Here (I think) that the complete video file is copied 1:1 and is muxed with the new sound track. Here I easliy run out of HDD (running a small SDD on a NUC), and when the PLEX “flushes” the files do to lack of space, the current transcoding segment is lost, at PLEX starts a new segment at the ending of the current segment. And therefor jumps foreward…
So, my solution will be to move the transcoding directory to the external drive, and this should solve my problemes
