Best Adult VOD Site?: The most popular VOD service in our guide is Hot Movies, which has tens of thousands of adult titles. You can use your minutes on any PC, Mac, Android phone, iPhone, iPad, Kindle or tablet. You can buy access by the minute (at 8.7 cents and up) or purchase unlimited viewing of any individual title for two, seven or 30 days. Our most popular flat-rate site is Video Box, which charges $9.95 per month for unlimited downloads from its library of more than 8,000 movies.

Prefer to Rent DVDs?: If you prefer to rent DVDs rather than download movies, compare online services at our Adult DVD Rental Guide. Most charge $10 to $30 per month to have one to three adult DVDs out at a time, with no late fees or return dates. A few rent individual DVDs for $3 to $5 each per week. A credit card is required to join any DVD rental service.
