It is sort of a weird problem I am getting. I have a Sony Vaio with a Pioneer dvd-rw Dvr-106D. it was working fine but then i upgraded to windows 7, and it's when my problems started. It says it is installed and everything, but when i put a data disc it does not read it or prompt me what i would like to do. But when i pop in a DVD, it opens up windows media player and plays it. If anyone has any suggestions on what I could do, i would greatly appreciate it. Have a great day.
