Hello Ken, That is a lot information for me, guess it's not a straight forward answer to the question (if my show will fit into one DVD?). One the ratio part, I change to 16:9 setting from PTE project, and when DVD burning option I also set the ratio to 16:9, and the DVD display on my widescreen fine (without stretching horizontally), however the top and bottom of pictures got cut off a bit. My pictures are of 1024x680 resolution. Thanks for your help. Cal,
