Saying you are using TDK DVD-R or Phillips DVD-R media does not fully describe the actual DVD Media you are using. To accurately describe your DVD media you need to provide the Manufacture ID and Media Code (Example- RitekG05). You can obtain the Manufacture ID and Media Code by using DVDInfo Pro (http://www.dvdinfopro.com) or similar software utility.

The problem is that it appears that your bargain Phillips DVD-R (1-8x) media that you recently purchased is substandard cheap, inferior, substandard DVD media.
Bottom line is that it appears that your recently purchased bargain Phillips DVD-R (1-8x) media is substandard cheap, inferior, substandard DVD media. Concerning the quality of DVD media.
