Download Movies Instead of Renting: If you prefer to watch movies instantly on your computer rather than waiting for a DVD to arrive by mail, visit Adult VOD Pod to compare services. VOD stands for video-on-demand. Purchase credits to view DVD-quality adult movies online or play a flat fee (typically $4.95 to $14.95) to download movies that can be viewed for a set period of time (e.g., 24 hours, a week, 30 days). Some sites, such as Video Box, charge a set monthly fee (in this case, $9.95 per month) for unlimited access to its entire catalog. Others, such as Hot Movies, sell access by the minute or per download.
