Thanx for your response.
I have nothing connected to the Jmicron. I have a SATA HD, and 2 Optical Drives in the Intel. The SH-S182M is set to slave of a Creative DVD Reader, which is set as Master.
Regarding Vista capable software, I had some problems with my Creative sound card software. So I unistalled it, along with every other program i had that could create a virtual drive (Daemon, Alcohol, MagisISO). The problem is still there. I'm not able to burn not even a simple CD.
The log in ImgBurn stops when it says writing lead-in or something like that. I'm not able to copy the log, as it freezes when i try to. Besides that, whay I see is that the program shows that the buffer is at 100%, but the Device Buffer never moves from 0%.
If you need any other info, please tell me. Thanx
