I have Optiarc DVD RW AD-7170S and it is only reading DVD Rewritables. I am using my video editing program, Premier Elements 7. I tried burning Taiyo Yuden DVD and doesn't burn. they used to work on that program. I just updated the DVD driver of 1.3 version instead of old version of 1.00. Why is my DVD drives only burning rewritables(RW) and not Taiyo Uden, and other DVD anymore, is there away to change the settings.. . cause I heard Taiyo Yuden are a great quality brand of DVD.. I used them for my customers, but now can't use them only Rewritables(RW)? Please help?
