Some shows not fully converting

Since updating to 2.5.2 I have noticed a few shows aren’t converting as they were before.
I get the first few seconds of the show but nothing else…

I have uploaded some log files to the ftp of 2 that have failed and 1 that has worked

I’m stuggling with what could be going wrong here
I have also tried 2.5.3 beta an the logs are from this version

I’ve done a bit of testing this afternoon and it works fine with MP4 unprocessed but not mkv

Your source video file is corrupted:

I am also having the same issue and i didn’t have mcebuddy previous to this version so I don’t know if a newer version is causing the problem

Changing to mp4 unprocessed fixes the issue

These are files recorded from Channels TVE mode - about 60-70 percent from this specific channel are having the issue
