I created dvds using DVDA. The dvds play on my computer, my dvd player and my xbox. The dvds will not play on my customers dvd player but will play on their laptop. I am using Pro 6, bite rate of {mbps) 5, frame rate 29.97, 16:9
Use only Verbatim or T-Y dvd blanks, and burn at a slightly lower speed if necessary.
If your customer owns a Curtis-Mathis player, encourage them to buy another brand.
