I have a philips DVDR1640P dvd/cd rewriter and cannot change the write speed. Well it lets me change it but when the burn begins the speed changes. I need to burn at 2x speed or the DVD's wont play in my DVD player. I pick 2x speed from drop down menu in Imgtool burn and when the DVD starts to burn the speed is 2.4x. I contacted philips and updated firmware, they said this should work but it has'nt. Can anyone help PLEASE

There's no significant difference between 2x and 2.4x speed; I don't think that a DVD player can detect THAT! However, the speed difference can also be caused by using DVD+R(W) instead of DVD-R(W) or vice versa. Note the plus sign and the hyphen! These are different standards; your DVD player may be abe to play only one of them (probably, the hyphen one). Read the manual of your DVD player (again), carefully.

You would think there would be no difference. I got the rewriter last year the one I had before copied at 2x speed and they worked in the DVD player, now when i copy them at 2.4x the message disc error comes up. I am using DVD-not+

As far as I know, the burner "communicates" with the disc, reading in the speeds that the disc itself supports. Perhaps, the reason why you can only write that particular disc at 2.4x speed instead of 2x is that you're using a different (lower quality?!) media... See http://www.digitalfaq.com/media/dvdmedia.htm for a media quality guide.

Now I have tried sony dvd-r 1x-4x, when i use this disc, i get no option, burn at 4x speed. When i use a 1x-2x disc it writes at 2.4x, I never had this problem with my old dvd-cd rewriter, and that is the only thing I have changed on my computer and the only reason i changed it was it broke.
