freitasm: Legally YOU CAN'T RIP DVDs in New Zealand, only CDs.
EDIT: MED FAQ about audio format ony.
I found this paragraph interesting:
The markets for audio visual works and music are evolving, they are different. There are numerous business models for audiovisual works that do not apply to music. Theatrical release, commercial rental (both physical and online models), free-to-air TV and pay TV do not have counterparts of any significant extent for music. It is also unlikely that consumption of audio visual works "on the move" using mp3 players and the like will ever be as ubiquitous as for music. It is not, therefore, possible to simply apply the conclusions reached about music to audio visual works.
It seems a bit out of date.
Theatrical release admittedly doesn't really apply for music. However, commercial rental certainly exists (physical - e.g. borrow CDs from public library, and online - spotify/google play music/pandora). Similarly free-to-air TV is probably equivalent to radio, and pay TV is probably equivalent to paid music services like the aforementioned sites.
"It is also unlikely that consumption of audio visual works "on the move" using mp3 players and the like will ever be as ubiquitous as for music."
Clearly this has changed with the advent of the smartphone.
I'd argue that the information they've based their conclusion on is dated, and there's probably a very good argument for format shifting to be applied for audiovisual works.
