i want to record a dvd from noncopyrighted material. i have an external dvd recorder but it only has composite inputs so the resolution is 300 lines or less. i have a notebook with a dvd burner. can i make a slightly higher resolution disc with this burner? perhaps close to 480i or is that not possible? i am using the hd output from a cable hd tuner. the tv show is not protected. i am making a dvd for myself. not for resale. this is just a technical question. i am not interested in making a\ bluray disc now. just a\ higher resolution SD disc.
