Problem with my new Pioneer 108, not reading disks?

i had a new Pioneer drive for xmas, so far ive had no burning problems, ive copied a few films from my harddrive and plenty of cd’s with the drive.

however it doesnt seem to want to play dvd or audio cd’s, when i place a dvd in the drive it reads it, but will not start to play the disk (im using power dvd).

my main problem though is that it cant read the cd enough for me to use DVD Shrink, i place a disk in the drive, it reads its there but when i click to open the disk i get a ‘cannot be opened due to a I/O device error’, not good.

i used DVD shrink several times with my old dvd drive and had no such problems.

do i have to install firmware or anything? Please Help
