Sorry...I forgot...

Its not a guarantee that your videos will sell or not...some studios new or old have DVD videos that do well and sell plenty and some just bomb!!!

Its very competitive, when your a new company...if your boxart is great and your content is excellant your chances are greater for you to succeed.

Its the sample as if you're going to open up a website...how did you know your site was going to do well or not? Don't you promote and market your site? What is the quality of your site? How does your site compared to others? What is different about your site compared to others?? The same questions apply when your creating a DVD.
