Here's something strange - Sonix brand 4x drd-r that burned from iDVD3 repeatedly at the 4x speed (actual time 17 min) takes 49 min in Toast 6. btw- Nothing else is different, same Mac system and same spindle of discs. When I tried the project from iDVD it burned the next one fast. Have any of you run across this type problem before? R.B.
