The DVDs I burnt at faster speeds (4x on a 4x DVD-R, 2x on a 2x DVD-RW) don't play smoothly or even stop. I successfully burnt perfect 4x DVD-Rs using 2X using Nero (it actually says 2.4x but close enough). Now I don't have a burning software that goes lower than 2x that support non-IFO format (DVD Decrypter can burn at 1x but only for IFO format. Please correct if I'm wrong). Can somebody recommend other software that can do 1x (I want to use up those 2x blank discs)? Preferrably free software. Thanks.
