I had some trouble opening my videos (mpg) with Quicktime on my Windows Computer. They run really slowly and got stuck every few seconds. In addition I could'nt hear any sound.

So I converted the videos to a datavyu.mp4 format. Now I'm able to open them via VLC-player without problems and the quality of the replay is satisfying. Unfortunately there is no sound and not even the symbol for the sound volume (which was there at the mpg-format of the video, but had no effect).

Did I do something wrong? Thank you for your help!

I don't think we've encountered this problem in our own lab, so I'm not immediately sure what's going on. Would it be possible to send us a sample file, so we can test it out?

Also, what version of Datavyu are you using? We recommend that users stick with the Quicktime player right now. Does your converted file work in the Quicktime plugin?

In the meantime we were able to solve the "sound"problem" by converting the videos to .mp4 or .mov. Nonetheless the quality of the videos played with Quicktime is inferior to the ones played with VLC-Player.

Now we are facing a new problem; although we decided to use Mac-Books and the Quicktime-Player, it is not possible to save our files properly. Datavyu just saves the spreadsheet with the columns and all the possible codes per cell, but doesn't save the already defined cell content (one selected code per cell). To be clear: the single cells and their on- and offset are safed accurately, but the content of the cell (defined code) is not.

Closing the video-file before the saving process doesn't help (we read about this in another question)

Thank you!
