Yes, the problems still occur when the files are on the hard drive. The computer that I created the files on recently was not working and had to be completely reformatted. I think that may have corrupted the files. I recreated the files on another computer and was able to get it to work. The only issue is that the video file will only play when it is located in the downloads folder. When I copy the video file to the folder with the rest of the documents and update its location in the files, it will not play. We can successfully run the experiment now so it is not necessary to fix this issue, it is just a little strange. Thanks for the help!
