There Have been a number of posts regarding the mysterious line 2195 Assertion Failed
Anyways I think I have found a possible reason for that.
the offending file is probably a MKV file. Matroska chapter specifications contain a ChapterUID tag. For each chapter in the xml file the UID needs to be Unique. I've noticed that Handbrake does not always make them unique. That's when I get this problem.
Solution: extract the chapters.xml from the mkv (MKVcleaver works for me). open the xml and change any duplicate ChapterUID tags to be unique. then use mkvmerge to remux the chapters back in. (don't forget to deselect the chapters track and add the xml file in the chapter section of the global tab.)
Hope This Helps
