From what I understand, the first most regulated industry is the nuclear power insustry. Second, is electoplating.
Producers from what I hear. The performer(s) get a small royalty, the author of the lyrics and the music get a piece and there is the publisher. Wish I knew more about how they split it but that's what I hear.
You can find insustry information from a 2004 survey at the related links and create your own pie chart. EXAMPLE: Transportation equipment manufacturing > Total cost of materials = $4,392,110,000.00
If your computer has a DVD player it should play, providing that the DVD player isn't limited to only playing DVD-r discs. There are a couple of types of DVD's on the market. DVD+R and DVD-R which use different burning methods. The insustry finally seems to be settling on the DVD-R format, but that doesn't mean that other compainies with DVD recorders have decided to follow suit.
