I have been trying to convert a large avi file. I am using the high quality option, so my file comes out to 8.gb. I tried vision express and got this message (your project currently requires more disc space than available on the selected drive.) I have plenty of hard drive space, and i am copying to hard drive. I also get this message when i am about to write to hard drive.(recording this project may be unsuccesful and could produce unusable results. do you want to still start recording.) and after it is done to hard drive it is only 1.88gb far below the size it should be. I was advised to use a dual layer disc but i am not sure if dual layer will play alright on a standalone dvd player. Can you play dual layer on a stand alone dvd player. Any help appreciated.
