i have a Pioneer A105 DVD-R writer which is supposed to write dvd's @ 4x speed however I have written 3 dvd's so far and they all take up to 40 mins as if 1 speed but nero states writing @ 4x.
the discs are white printable surface ritek's and are supposed to be 4x media so whats the problem?
On the fly ??
If no then need 10-15 min to make image and 15-18 min to write.
If the system is unstuble or the prototype dvd is bad then make long times
Your problem is likely the Riteks. Some sites are making wild claims about them being 2x and 4x compatable, but if you read the fine print, you discover that you need a specific version of firmware in your specific burner or else it automatically kicks back to a usable write speed, typically 1x.
The A04/104 specifically needed firmware v1.31 or else those same "2x certified" Riteks were only 1x. Frankly, I put them in the same class as Princo.
Just remember, you usually get exactly what you pay for... :D
Pioneer (Jap) recommends this utility to test compatability with your drive. It will tell you lots of goods that it reads from the info pressed into the DVD/CD at manufacture--but most importantly, it will tell you what speed you can burn the media at.
Unzip the exe file to a file and run it. Load the media (blank or burned) and select your drive. Click "Extras" from the drop down menu and select "Disc Info".
