I waited for a long time to see which DVD standard would take over, but one never did, so I finally just got a burner that would handle both, and its hit and miss when trying to send a disc to someone as to whether their readers will read it. Biut at a dollar a disc, it doesn't hurt to send dupes.
The best CDs are the Diamond. You can't buy these in the stores. The Platinum is the next best. I wouldn't buy anything less than that, myself.
