Recently when i burn dvd's/cd's the device buffer is at 98% (normal for me) and occasionaly drops down to like 13% and back up to 98%. when this happens the dvd skips, doesnt work at all. This used to happen to me when using a Sony DRU-530A, on a completely different machine, and i ended up buying a new drive. As of now i do not want to buy a new drive and was wondering if there is anyway to fix this? thanks.
