On my last production, I used 3 DVX100B's to create the first ever TRUE kosher cooking DVD. Now that this DVD was successful, I want to make a new DVD with new recipes etc, but i'm ready to BUY instead of rent. Since my final product will be on DVD (and in SD form) does it help (at all) to be using an HD camera? Should I be using an HD camera in SD format if i want higher quality videos?
