I'm trying to open videos to work on coding in Datavyu and I finally got it to allow me to actually download the files (before I was getting the error message saying the Quicktime Java Libraries were not found), but now once I open the file it says that the track timing information could not be calculated. I have tried two different forms of the video files too, including .mov and .mpg. I'm not sure what I should try to fix the error other than perhaps uninstalling then reinstalling the quicktime player.

Datavyu's uses QuickTime to play its videos. If your videos do not play externally in Quicktime, then they will unfortunately not play in Datavyu. The playback issues should not be due to the custom download but you can check to see if your videos run smoothly with the standard download of Quicktime.

I recommend using Apple support resources to make your videos play in Quicktime ( and then they should play in Datavyu.

Are you able to open and play your videos in Quicktime and what version of quicktime are you using?

You do not have to reinstall Quicktime.

I'm using QuickTime 7, the latest edition. The QuickTime player doesn't seem to be working either though and states to install the Apple Application Support, instead my videos have been playing on the VLC media player. I figure it could be due to having to only upload a certain aspect of QuickTime in order to be able to get the Datavyu program to recognize the java libraries.
