I have a Teac DVD+RW DV-W58E and lately its been only burning at 0.6-0.9 X. I use Dvd Decrypter and Dvd Shrink 3.0 and always use the same media 4X Memorex and never had problems before. Always burned at 4 X so it only took about 15 minutes and now it takes over an hour. I noticed it when I got down to about six disc left so i thought maybe it was just a bad batch so after I used those up I went out and bought more and sure enough the same thing. I even borrowed a disk from a friend just to make sure it wasn't my media. I have no clue what it could be. I haven't changed anything on my computer I always do the same exact steps when I burn a disk. Any idea's would be great thanks.
