dvd shows as being downloaded and ready but if i want to try before installing,i can not?? i get the reddish orange screen
but no icons at all??

Prior to burning the Ubuntu iso files to the DVD as an image, did you do an md5 checksum to verify the download? See the link below for the correct md5 checksum for the different Ubuntu iso files.

What is your graphics card? You may need the nomodeset parameter on boot.
