[Matroska-devel] Tagging MKV files

Thanks for the quick feedback. I suspect it's #3 that's causing my problem.
Just so I understand, is the SeekHead always contained in a Segment, and
then all offsets are from the start of that segment?
Thanks again for the help,

You've obviously done something wrong ;) Three things:
1. Look at your file with mkvinfo -v -v and look for "suspicious"
things. I cannot really be more precise; things like "unknown
elements" or "dummy element" would definitely be suspicious.
2. You can also use "mkvmerge --identify-verbose yourfile.mkv" before
and after your modification. It should show identical output safe for
the tags. However, this is a pretty superficial test, so you cannot
derive validity from a successful comparison.
3. The seek head positions they point to are relative to the segment
position! Check that with mkvinfo -v -v and compare it with known-good
