I use ConvertXtoDVD, and after i convert the movie, as usual, a message pops up saying please insert a writable media disc in the selected drive. I do so, and it wont pick up that i inserted the disc. And there are no scratches on the disc, or anything wrong with the disc, un less its just a crappy brand. I am using Magnavox DVD-R 1-16x speed. My DVD Drive is a Matshita DVD-RAM LF-D521 A116, thats what it says in ConvertXtoDVD, but on the outside of the drive, it says panasonic DVD multi recorder. Someone please help me.
