I have a problem with my PIONEER DVR-215 1.22 drive.
I had Windows XP Pro SP3 and I flashed this drive with firmware modified by your application for making book-type setting.
Every thing was OK under XP. I’m mainly using Nero Burning ROM 22.214.171.124a
My problem is under Windows 7 x64 that i recently installed on my station.
I can successfully use Nero Burning ROM 126.96.36.199a in 7 x64 for example on my Optiarc AD-7241S 1.03. I mean it is changing the booktype. Difference is that I can see in nero log that it is changing the book type like regular choosing the book type for an LG drive.
On Pioneer didn’t see any message for changing the book type to DVD-ROM but worked on XP.
In 7 x64 it cannot change the book type.
On Nero it can be verified after burning and all process is finished OK, but I cannot read the content of the disc.
I also tried ImgBurn 188.8.131.52 thinking that it can be an issue on Nero on win 7, but also had problem. It can write all the information on the disc, but on the verify step the ImgBurn is blocked. The step is in the log named as “Synchronizing Caches”. After restarting my PC I saw that I cannot read the disc.
In all situations in Nero CD DVD Speed 184.108.40.206 I can see that the book-type is DVD+R, not DVD-ROM. That’s why I’m thinking it cannot change book-type when using win7 x64. Also the disc appear as being open, even if I tried not to make an open session disc.
I also have a PIONEER DVR-112D 1.28 flashed like this DVR-215 1.22.
But didn’t make any test on it yet.
I haven’t tried DVD-R on DVR-215 yet.
I’ll make some more tests in the future but only next week I’ll be able too.
Hope this info is enough for you maybe to understand what is the problem that cause it.
