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

One of the favorite jobs of the movie buffs, is to know the hit list that has topped the market both commercially and popularly. One of the main indexes of a popular film is that it has to be commercially successful. If the film were economically viable, it would 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. Almost all the best selling film DVDs of 2007 have fallen under this headrest.

Now, the distributors are not limited to getting their revenues from the ticket selling only. There are 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 also.

A film like "Transformers", which topped the chart in both rental, and Box office is also a hit in the toy market. It has been in one of the best selling film DVDs of 2007. There have been all sorts of Transformers merchandise; toys, caps, t-shirts, guns, window valance, poster, comforter, party mask, lunch plates, communicator, monopoly games and everything.

'Transformers' is a retro cartoon, which became an instant hit when it came on to strike the big screen in 2007 as a live action film. In 1986, The Transformers, the Movie was the first full length film based on the cartoon series. The story of Transformers goes like this; it is the fight between two robotic clans. One is the good Autobots another is the evil Deceptions. The two giant robotic clans posed a great threat to earth. It was left for the hero, a teenage boy two save the day.

One of the best selling film DVDs of 2007 was" Chicago". It was a huge success both on DVD and the rental chart. Not only the sales were on high but it also was listed on the Top 10 chart some time or the other.

'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', 'Fantastic 4: Rise of the Silver Surfer' and 'Ratatouille' are some of the hits of 2007.

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

Rippers target the current year released films. For example, Scene releasers would take on the best selling film DVDs of 2007, and rip 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 in compression Codecs like Xvid, DivX or x264 the quality is reduced by mere 20%, with file size coming down 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.
