I have been burning DVD's for a while now, and here are my experience's with Nero Burning Rom (currently using 6.6.0.15). Firstly if you get a Power Calibration Error message this can happen with any make of drive + any firmware and any brand of disc. It doesn't mean your DVD lazer is dirty as it can happen with a brand new drive. I found I got a power callibration error message every time I tried to burn a disc when I had a brand new Pioneer 107 in an external USB2 enclosure (I also put the same drive inside the PC, and still got error's but not as often). I have been searching on the net and found a couple of "solutions" I have a disc burning from the hard drive right now so wonder if it will work by the time I have finnished writing this post? Here's my findings: To Avoid "Power Calibration Error" messages: Go to Computer Management> Services and turn off IMAPI CD-Burning COM service "Startup Type": Dissabled In Nero. Change Ultra Buffer Size from automatic to Manual (max size is 80Mb). Bugger!!! BURN PROCESS FAILED. (Philips 4.7GB DVD-R 1-16x) So those two solutions above make no difference at all. (currently using Pioneer 108 with latest 1.20 firmware. I have also had one of those tower duplicator cases and used "on the fly" to copy DVD's, but ended up with more coaster's than working discs (even at low speeds). Tried just about every brand of media. So hoping when I get a new DVD reader Asus DVD-E616A that will make things better. The amount of memory & processor speed does not affect burning performance either. I now have 3.2Ghz processor and 2.5Gig of Ram and still get the same burning problems.
Need to understand what it means. I can see from your referance to cleaning laser heads that you do. For others that has nothing to do with power. It is for calabration of the laser head for the write stratigy to be used for the media it is sensing. IMAPI could cause the problem in some cases. It would have to be calabrating the head on insertion of the media so disabling it could stop it from happining. I dont reccomend disabling it though just set it to manual so if you use apps that call the service it will then load the process for the app. I hate to say it but those disks may be the problem this time. Philips has been known to use cmc for there media. That is more then enough on both ends. But to say amount do not effect would lead people to think a little is ok when it just is not. More then enough is good not enough is bad.
