Following chat is purely based on my experiences, not technical documents. So, it might be wrong :-)
Non-data (music/video) CD/DVDs are structured based on tracks etc. When you put the disk in computer the software reads the information and handles the data as files. So, when you copy the files to disk it becomes a data disk.
Usually, the software players can handle that, i.e. as soon as it "sees" the typical video file structure it will track down the required information and play it back as a video disk. When you put the disk into stand-alone players they don't know what to do with the data. Of course, there are some players doing what a software player does, i.e. you can replace files.
I know that California and Arirang has problem.
