Phillips CDD3610 and Mitsui media
 

This is really weird. I have a Phillips CDD3610 and have been burning discs fine with Sony media. I recently purchased some Mitsui brand discs, and when I burn using those, it seemingly burns the entire disc (whole audio tracks), but then I find that it only writes empty audio tracks to the disc, which would have only taken several minutes, rather than the burn time of an entire disc. When I use the Sony discs in the same manner, it works fine. Does anyone know what is going on?
