hoi all, i bought a pioneer dvr-109 at a computer fair and installed it physically in my pc, taking the place of a fully functional cd burner. i also istalled nero suite. the first day was fine, i even burned a movie no worries, but soon after things got a little weird. The drive stopped recognising the disc that was in the tray, it would just show the data of the previous disc or none at all. I built my own pc and have had no probs for a long time, i just removed the dvd and put the cd burner back in and it works fine as it did before, does anyone know what might be wrong with the dvr-109 or its setup?
