As you can see, raw data is being displayed, instead of the actual sub content (in this case, just the word "Luna"). This is with Matroska files only. I downloaded the "Tokyo Mew Mew" test from
http://matroska.free.fr/samples/ and get the same result.
Subs display properly in zoom and in media player classic.
Love your player and would like to use it for everything. Using build 803.
