Can you provide some publicly available sample videos that don't play?
The following services might be good sources:
http://www.demo-world.eu/2d-demo-trailers-hd/
http://samples.mplayerhq.hu/

I have a list of supported formats and codecs (should update it for
OTA-5!) at
http://sturmflut.github.io/ubuntu/bq/2015/05/31/hacking-the-bq-part-3-supported-media-plugins-and-codecs/
. MKV with H.264 and AC3 should be supported.
There is a very old bug report I opened last year that could be related,
https://bugs.launchpad.net/touch-preview-images/+bug/1356587 . I just
retried some of the files from back then on my Aquaris E4.5 and all seem
to play correctly now.

We can't read minds ;) If your issue isn't known and planned to be fixed
with an OTA, then waiting for an OTA will most likely not fix it.
cheers,
Simon
