text: memorex dvd burner? my dvd burner is capable of burning at x16 but whenever i burn a dvd it says x12 even though i have it on max burn setting. is there any ideas as to why it does x12 instead of x16 and how to change it.  the software is nero 6. not all dvd writers can achieve what they claim.  "once again we note that speeds shown on the box and in the technical specs are purely theoretical. makers should be honest with us and change statements like "writes at 16x" to "writes at up to 16x." and maybe add this disclaimer: "your mileage may vary"..."  16x speed is an optimal/max speed.  if errors are introduce, the speed will fall back to recover the last data.  errors may come from the data source, (hard drive), the ide connections (cables), the optical systems (dirty read/write heads), and even the blank media (low quality dvd)  are you using x16 blank media?
