Yes, that does stop the error when browsing but is still stopping me from playing those files!

Nothing else I can do/try?

Try remuxing the files into something else?

we need a short video sample to reproduce the issue. I dunno why the are asserts still shown since ffmpeg was compiled with -NDEBUG/--disable-debug.

The solution for this issue may have been posted in other threads, but I was experiencing the same error; after research on this forum and elsewhere, I had to post my resolution:

A movie I had recently imported to my library generated the utils.c error. MediaInfo showed Chapter listings, and as indicated in other posts, I noticed that each chapter entry was duplicated:

Code:

Chapters:
    Chapter #1 - 00:00:00.000 - "00:00:00.000"
    Chapter #2 - 00:00:00.000 - "00:00:00.000"
    Chapter #3 - 00:04:28.018 - "00:04:28.018"
    Chapter #4 - 00:04:28.018 - "00:04:28.018"
    Chapter #5 - 00:10:30.547 - "00:10:30.547"
    Chapter #6 - 00:10:30.547 - "00:10:30.547"
    ...

Research at the MP4Box website indicated that the chapter marker names (in quotation marks above) must be unique; I copied the chapter info into a text editor and corrected the entries thusly:

Code:

00:00:00.000 1
00:04:28.018 2
00:10:30.547 3
00:16:37.330 4
...

Finally, I used the MP4Box command-line interface to import the corrected chapter entries to the video file:

Code:

C:\Program Files (x86)\Yamb>mp4box "I:\Movies\Movie Name (2012)\Movie Name (2012).mp4" -chap "chapters.txt"

No more errors now when I open the movie in XBMC!
Hope this helps...
