Why will DVD-r not play back?

Answer 1

When most people talk about a DVD disc, they are talking about the sort of disc we would use in our DVD players to watch a movie on the television. A DVD-R is a recordable disc, generally with a capacity of about 4.7GB. With the correct software and a compatible drive you can store anything on a DVD-R. The most important question is the format that has been used to store the information on the disc. If you are trying unsuccessfully to play a disc on your computer that will play normally in a domestic DVD player, it is likely that you need to install some software that will allow your computer to interpret that sort of information. If your disc is not one that will play in a DVD player, then the information is in a different format. Try browsing the disc in Windows Explorer to see what information is store on it and in what format, then search the internet to find a suitable application to use with that type of file. Of course, from your question it is impossible to see for sure how you are trying to play back the DVD-R. If you have made the disc on your computer and are now trying to play it in a DVD player, it is likely that you have not put the information onto the disc in a format the DVD player can understand. Again you will have to find a suitable application that will allow you to create a disc that will do the job you are trying to do.
