PlayOn Videos fail to convert

Previously I was able to use MCEBuddy to convert PlayOn Cloud videos with no issue. I could trim the ends, and use the markers they embedded to edit out any commercials. Unfortunately, when I went to do a recent batch of videos, I get nothing. It outputs no file and there seems to be an error with FFMpeg but I don’t know how to fix it. In this case, I was simply trying to trim the ends off using MP4 (Unprocessed) without even removing any commercials. The videos play fine in Channels and in Quicktime so the files themselves are otherwise fine. I’m not sure what to do. Any advice?

Here’s a log of one of the videos that didn’t convert.

It’s a bug with the latest PlayOn software update. See this topic for more details and workarounds
