Hello, so I been having this problem for about a month and cannot figure out what is going wrong. I have tried exporting multiple 1 - 3hr projects and about half way through each of them the encode fails but only on MPEG 2. I looked around and our MPEG 2 codec is the latest. I have had this occurrence on 3 identical workstations.
