Have you ever burned a DVD at the office and gotten home, only to find it won't play in your dvd player or computer? Digital media experts say it's not rare to get a rejection when playing recorded disks.
"They would get some sort of error message, or incompatible format. In some cases, they will say the disk is dirty or there's something wrong with the disk." or you'll see dropout or the disk might freeze.
What's causing the problem? "well many of the older dvd players in particular, and poor quality dvd disks. When the data is recorded onto them, they tend to have problems."
In a recent study, researchers tested 14 different models of dvd drives. Each one was tested with more than 50 brands and types of recordable discs. "We found unfortunately that no one device was able to read all the media, and no one piece of media was readable in all devices." Physicists came up with suggested data and quality standards. "The idea is to present this information to the industry so that they can have a benchmark, and therefore the whole industry will reach that goal of much higher compatibility."
