I'm pretty sure thats why its called "ConvertXToDVD"......
but all kidding aside, if you already have a movie on a DVD the other method of putting it on a stick would be this.............
Insert the Disc with photos and sound (close any autorun)
Go to My Computer
Right Click on the CD/DVD drive (with your photos and sound in) and select open
Click on Edit (in Toolbar) then Select all
Click on Edit (in Toolbar again) and select copy
Close the folder
Insert your Flash Memory stick and select Open folder to view the files
Click on Edit (in Toolbar again) and select paste
All done Copy and paste...
