It's great. Really great. Ensure you have 1.65 firmware from the Pioneer Support site. To tell what firmware you have, go to properties in Windows and it'll be in there. Also the burning software should also tell you. Firmware 1.55 burns unreliably on the cheaper media.

If you use Windows 98 or FAT32 disks, then you'll need to ensure that, if you are using PrimoDVD software, the 'px engine' is updated from the Prassi support site. Otherwise it'll stop at 4GB.

Takes about an hour 15 to burn 4+ GB.
