I had an original DVD+ burner by Sony in my Compaq laptop that I could not speed control even in Nero. Unknown to me at the time was the fact that it was only a 2X burner (not mentioned in the documentation). It always appeared like the media speed dictated the speed of the burn even in Nero and even when I would select a lower speed. So I switched to CDBURNER XP Pro which does not use the ASPI layer but rather XP's NTSI layer. NERO comes with it's own ASPI layer. With CD Burner XP PRO (Free ware) I could control the speed of the burn (fewer coasters).
I swapped out my Burner for a NEC ND-6650A- DVD-/+ DL 8X's burner but still had the same issues if not using CD Burner XP Pro.
I still had problems with other apps the allowed burning. I tried instaling the ASPI layer on my own using various instructions from the Net at the time and was never successful until now. Did I mention that MM was unable to detect my burner until I installed the Adaptec ASPI layer.
The package can be downloaded from ZDNET downloads. URL provided below.
I used the exact line given as an example in the install instructions. Ran it in the "RUN" command box with the example switches - executed the ASPI verifier to see the changes and rebooted my system. I then started MM and burnt my first BLUES MP3 CD. Unless you buy the Gold MM you are restricted to a lower burn speed.
I am new to MM and probably will upgrade once I have played around with this almost "do it all" program.
