Help needed for DVD survey.

Hi all,
        I'm studying for my Master's Degree in Design for Digital Media.
I'm currently conducting research into the possibilities of DVD
interactivity.  Specifically, how much people want to interact with DVD
content on their televisions.  DVDs like Harry Potter and the Philosopher's
Stone ask people to engage with the DVD more and solve puzzles to unlock
extra content.  This is more like a traditional CD-ROM interface being
adapted for DVD, instead of the straight highlight that you find on most
DVDs.

If you can spare a few minutes, I'd be grateful if you could answer the
following questions (just hit reply and fill in your answers).  Your name
will not be used in any documentation I produce.  The only purpose of this
questionnaire is to guage public opinion on this type of content.

1(a) Age:
1(b) Sex:
1(c) Country:


2.  On a scale of 1(lowest) to 5(highest), how computer literate do you
consider yourself?


3.  Have you ever looked at DVD-ROM content that comes with a DVD movie?  If
so, would you like to see content like this playable on a TV?


4.  (Region 2 only) Have you seen the My Little Eye DVD?  What did you think
of the Interactive Browser mode?


5.  Which of the following interfaces would you prefer when accessing extra
content:
     (a) Highlight - just highlight the option on the menu and hit Enter
     (b) Puzzle - solve puzzles to unlock content and hidden features
     (c) Explore - explore rooms and highlight objects to access content
(e.g. roll of film on the floor for deleted scenes)
     (d) Choice of all three on the one DVD


6.  Do you think DVDs should be more interactive or should they be left as
they are - just the film and some menu screens?


Thanks for your help.

Gareth.
