After copying the dvd movie using dvd clone 2, it plays well on the stand-alone dvd player, but after half way thru, the player would freeze. I played it on the computer's dvd-burner and it does the same thing. What gives? I am using the hewlett packard dvd+rw with the bit settings set to dvd-rom and burning @ 4x. The dvd burner is io-magic 16x dual-layer burner. Thanks.
