What is the command-line option you use to create the matroska file ? Or
do you use MMG ?
It's more than strange that the video will play with audio in sync but
you have no time bar. I don't even know how that's possible in VLC...
Alternatively can you upload a small part of your mux (you can try to
mux in 2 parts with a max of 5 MB for each part) somewhere so that we
can have a look at the file ?
