Veronica,
First, this is NOT legal advice! Even so, this is how I would do it...
The Copyright Warning is easy. Get a copy of the FBI Copyright Infringement Warning and Title 17 of the US Code graphic, or just include a title page with the verbiage from Title 17.
If you need the graphic, I will be sending a copy of one to everyone who is subscribed to my eNewsletter later this week. Let me know if you need the download.
As for the disclaimer, the standard legal disclaimer verbiage from any workout product should suffice. You just need to cover your bases stating that it is the exerciser’s responsibility to seek medical attention confirming that they are health enough for physical activities.
We’ve all heard, “Consult with your physician before beginning this or any exercise program.â€Â
If in doubt, however, see an attorney!
As for the technical aspect of where to put the disclaimer, I would place both the FBI Warning Graphic as well as a graphic containing the disclaimer, along with an audio of the disclaimer begin read in the track of your DVD that auto-plays on insertion of the disk. Different DVD authoring software handles this track differently, but most good authoring solutions have a way of doing this. That way, the viewer MUST see your disclaimer before the primary menu is reached and a choice of which workout is to be viewed is made.
Good luck!
