The invasion of DVD has made people go gaga over the quality of home entertainment. Producers and distributors of the films that were earlier printed on CDs now have gone on to put their films on DVDs and Blu-ray disks. All the best selling film DVDs of 2007 have turned out to be a huge hit with people across the globe.

One of the favorite jobs of movie buffs is to find out which movies have topped the market both commercially and in terms of popularity. One of the main characteristics of a popular film is that it has to be commercially successful. If a film is economically viable, it will also be a hit in the box office. Nowadays the spread of mass media in every form of entertainment has provided some cost cushion for the distributors.

Now, distributors are not limited to getting their revenues from the sale of tickets only. They also get revenue from DVD and CD packaging, overseas marketing, selling of audio rights, and online film viewing. A trailer on the Internet publicizes the film quite a lot in the pre-release market. There are other promotional activities as well.

A film like Transformers, which topped the chart in both rental, and the box office, is also a hit in the toy market. It has been one of the best selling film DVDs of 2007. There have been all sorts of Transformers merchandise: toys, caps, t-shirts, guns, window valances, posters, comforters, party masks, lunch plates, communicators, and monopoly games.

Transformers is a retro cartoon, which became an instant hit when it struck the big screen in 2007 as a live action film. Released in 1986, The Transformers, the movie, was the first full-length film based on the cartoon series. The story of Transformers is the fight between two robotic clans. One is the good Autobots and the other is the evil Deceptions. The two giant robotic clans pose a great threat to earth, and it is left for the hero, a teenage boy, to save the day.

Another best selling film DVD of 2007 was Chicago. It was a huge success both on DVD and the rental charts. The sales were high and it was also listed in the Top 10 chart for some time.

The Hunted, Finding Nemo, The Matrix Reloaded, Bourne Ultimatum, The Lord of the Rings-The Two Towers, Stitch, the Movie, Live Free or Die Hard, Shrek the Third, Ocean's Thirteen, Spiderman 3, Rise of the Silver Surfer, and Ratatouille are some of the hits of 2007.

All the above-mentioned films have made good business in the box office, which propelled their success in the DVD market as well. One of the problems with film DVD selling is piracy. Film pirates are now ripping off DVDs to Xvid rips of 700 MB and distributing them over the Internet for free.

Rippers target the latest films. For example, Scene releasers have taken on the best selling film DVDs of 2007, and ripped them to high quality AVI, MP4 or MKV files.

The size of a single channel DVD is around 4.7 GB. The average data rate is around 8 MBit/s for the video. However, when the film is ripped using compression Codecs like Xvid, DivX or x264 the quality is reduced by mere 20%, with file size coming down to under 1.5 GB. This is acceptable for all the downloaders who are getting to see old and new releases in awesome quality without having to pay any money at all.
