I am looking to see if anyone has had a similar issue with windows 8. Using the VLC Player (the other players also) in OpenLP on my windows 8 Machine gives me a freeze/ jump in the first 5 or 6 seconds of the video, audio plays but video freezes. Most of our videos are in MP4 MOV, but other formats do the same. It plays fine just in the VLC not in OpenLP. If I have all the same settings in Windows 7, Vista, or on a Mac it plays fine. Is this a windows 8 glitch or possibly my hardware. The windows 8 has an AMD A6 4400M APU 2.70 Ghz with 4 GB of RAM. Which is the same as the windows 7 PC. Thanks for your help.
