Comment 8 for bug 719296

I have tried a couple of things now. My other machines were not powerful enough to run OpenShot (one is a real oldie and the other an old windows machine with too little memory to install OpenShot running a live CD) so that did not work. then I tried AV Linux live DVD on my main machine. I noticed that the OpenShot version there was not the release 1.3, but the alpha1. Anyway the timeline played fine there. So either the problem lies in the release version of 1.3 or in the combination of Mint and 1.3. Not very likely though, since I had the problem in both Mint 9 and 10.
