I'm trying to play a CD with a police interview. I am told that I must use DVR Play, but when I try to download, it says "not compatible" or something like that. I have an Apple.
If the file is a common video file, you can try installing a video player. For example, VLC should be exactly what you need to play the file on your computer. Download and install the application then use File > Open Media and browse to your file and VLC will play the file because it has support for a lot of file formats.
