During the recent conversion of the videos into iphone format some of the videos need to be fixed and reuploaded. The above mentioned video is one of those and I will fix it in a day or two. Thank you for your patience.
About the Financial Options tutorial, it was pointing to the Purchasing module Financial Options video and hence the confusion about inventory organizaiton. In Payables implementation you do not need to create Inventory Organization (unless you are using a vision install). I have fixed this video.
