Hey, thanks for responding.
1] K-Lite CODEC Pack was installed on January 2013 and then appears to have a new folder version 31st August 2014
2] Your VP9 is Build 562. The very last Builds were either 1147 or 1146. Should I try VP9.0e? Will my configurations files still be viewable on this newer build?
3] 2TB on C-drive with 1TB still free and 1TB internal storage (again, half is free) and another 1TB external drive.
4] I usually experience issues with AVI and MKV music video or movie/show videos in SV so I convert them in to MP4 before editing them in SV.
