i read another thread about these but my question is a bit diffy. I loved the maxell dvd's i was using but i also notice that the disks comes with warnings of downloading files for your burner to utilize the disks correctly. i am using a cheapy micro advantage dual layer/format 16x and i noticed when burning my dvd's using the maxell disks with shrink they came out wonderfully 'cept for re2 which i know know why after visiting this lovely site. now my mamorex disks are coming up with invalid disk errors on my player. out of 15 successful burns and 3 bad burns i figure not bad,but these mamorex disks won't burn as fast as my maxells did(12000kbs versus like 3000k on the mamorex) could the burn speed make that much of a diffy as to why they will play on my pc but not my stand alone? i am using dvd shrink 3.2 and nero 6 OEM Suite, my burns do take awhile to do as well but i figure thats cuz i only have 500mhz with 196MB Ram.
