Hi Ger, Thanks to email me in private even I receive automatically all bugs reports (and even sometime I lost few :-( ). It will be interesting for us to know what you have running OS in a terminal. The best will be to use gdb (although sometimes the output is mysterious for us.:-( Could you do like in this thread ? http://openshotusers.com/forum/viewtopic.php?f=12&t=180 If not, it will be nice to have the output of the terminal. The 0.8.8 version of MLT is certainly the best stable version since a long time. Thanks a lot to help us to become OS better. The next version will introduce Libopenshot and a lot of bugs coming from MLT will disapear. Be patient, even it will be the next version, she won't come tomorrow. We have a huge work to do for that but we will begin after Scale11x. Finally. 2013/2/23 Ger Luijten
