DVD burning: a business issue?

Making copies of DVD movies on the office machine may seem like an excellent idea to some of your employees. But what issues should Australian enterprises and IT departments be aware of?

With employee use of the Internet and e-mail of growing concern to Australian enterprises, electronic usage policies are becoming an increasingly important part of an organisation's procedures. These polices are also beginning to extend beyond employee's use of the Web, to include equipment such as DVD and CD burners.

Matthew Hall, an information technology partner in the Sydney office of law firm Phillips Fox, urges caution to Australian organisations that allow employees access to DVD-burning capabilities.

"Anyone who is providing a DVD burning capability, without making it clear what the permitted use is of those devices...[is] running a significant risk of being pursued for indirect infringement by authorising the infringing activity to occur," Hall said.

Hall uses the example of a case in the UK, where a phonographic institution sued an Internet cafe, because it had allowed users to download music and then burn this to CD in the shop.

Nor is simply having an electronic usage policy necessarily enough. While Hall said that these issues were obviously always on a case-by-case basis, organisations would probably have to do more than just say 'this is our policy'. "There will be some circumstances you would have to do more than implement and promote a usage policy, in order to avoid an argument that you'd authorised infringement," he said.

Although it would be more likely that it would be the company, or management of the company, which would be seen as authorising the infringement in these sorts of situations, Hall said it could also potentially extend to the IT department or other people in the organisation.

Hall suggests that if organisations were concerned that DVD burning was taking place, in addition to monitoring the electronic use policy, they could have staff undergo training about acceptable and unacceptable use.

It may even come down to looking at who in the company has access to the DVD-burning equipment. "Certainly you need to consider where it's connected--what people properly need access to undertake the proper functions of their job," Hall said.

Likewise, Phillip Hourigan--a partner in the digital industries group at law firm Deacons--suggests enterprises look at the content which is being burned on DVD machines in the workplace.

If it's content which is licensed to them from someone else then they need to look at the terms of the license to see if copying under any circumstances is allowed, Hourigan said. "If it's for distribution you'd really have to wonder if it was going to be authorised copying," he said.

In addition, Hourigan said that if the content had its own protection mechanisms built in--such as encryption--then amendments to the copyright legislation prohibits people from circumventing that copy prevention, except in limited circumstances such as error correction, authorised back-up, or security testing.

Hourigan also highlighted the importance of looking at which employees have access to the DVD burner. "You would generally avoid networking any of this kind of equipment, so it's only going to be available next to a single desktop PC," he said.

This includes a company's approach to physical security to IT resources. Hourigan described the IT department as potentially ending up as the "meat in the sandwich" if they were asked to make copies of material. "It may be a broader organisational question, as to what controls [are put in place] in terms of making requests to IT for things to be reproduced," Hourigan said. "Policy and procedure really does have a very important role to play in all of this."


DVD copying methods and preventative measures

How are my employees copying DVDs?

DVD copying is a matter of access to two things: access to a suitable DVD-burning drive; and access to copying and (in most cases) file conversion software. By far, of course, the easiest way to prevent your employees from illegally copying DVD titles on a work burner would be to limit/prohibit physical access to the burner, but that isn't always possible or desirable.

The majority of DVD movie discs come in two major formats--single-sided single layer discs with a 4.38GB capacity, and single sided dual layer discs with a total capacity of 7.95GB.

Some of the very earliest run of DVD releases used a doubled-sided format that necessitated flipping the disc over. However, these have become rare, as they're technically more scratch prone and offer very little printable surface for disc identification. The trend has been to move towards multi-disc releases in the 7.95GB format rather than continue with dual-sided discs.

The first challenge to any DVD copier is to remove the level of encryption that most DVD discs carry. While the promulgation of software designed to remove the CSS encyption has been the subject of some legal action, the software itself continues to spread and improve.

DVD burning drives of the type reviewed here only burn to single-sided single layer discs with a 4.38Gb capacity. Copying a disc that only contain that single layer of data is a simple matter of having access to software that can remove the CSS encryption and then burning the disc in the same manner as a normal CD-R/RW.

Dual layer 7.95GB discs present more of a challenge to the prospective copier, as there's no way to exactly copy 7.95GB of movie files onto 4.38GB of space. The solution lies in downgrading the quality of the copy via the use of a number of freely available utilities; by reducing the bitrate of a movie file it can be shrunk down in essentially the same manner as video streamed over the net is shrunk. Depending on how much of the 7.95GB available on a disc is used will determine how much compression is required; the other open alternative is to drop additional features or soundtracks.


What can I do to stop my employees?

From a technological perspective the simplest way to prevent this kind of conduct on a work machine would be to lock down the ability of users to install additional software on any system with access to the DVD Burner. While most commercially available burners do come with copying and archiving software, none of them come with the utilities required to remove DVD encryption and to compress the files on a DVD. The tools required for DVD decryption and recompression aren't difficult to locate with a simple web search, but if users can't install them, you've stopped the problem at its source.

If you're using DVD purely as a data archival format, you do have another option open to you, at least for the time being. The rival DVD-RAM format is highly suitable for multiple rewrites and at the same time completely unsuitable for playback in home DVD players. The issue with DVD-RAM is that the format is falling behind in sales compared to the DVD format writers, and as such locating drives, blanks and spares may become a challenge in the near future.
