I am having issues with avi files created with the new version of Camtasia 8. They are using a new codec tsc2. I dont have problems with the old versions AVI files which uses codec tsc1. What happens is that I have blank spots in my video created by Camtasia. Most of the 45min long videos are there but every 15 mins or so of video there is a spot about 5 seconds long where it is blank. The original camtasia file when watched outside of sony Movie Studio in the same spot is just fine. I am wondering if there is a fix for this or a codec that can be put into the Movie Studio program files on my computer somehow. I am using Movie Studio platinum 9
