Different stances in respect to the 'legal' aspect of this question have been made over the years and it's not real clear. I can tell you that the 'fair use' portion of USC Title 17 says:
"In determining whether the use made of a work in any particular case is a fair use the factors to be considered shall include —
(1) the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes;
(2) the nature of the copyrighted work;
(3) the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and
(4) the effect of the use upon the potential market for or value of the copyrighted work."
Generally accepted is the ability to back up something you own if not for commercial perposes. The thought is that if you own it you fulfill the final requirement of not impacting the market for the copyrighted material. Keep in mind I mean a legal copy of the copyrighted work produced with the permission of the copyright owner not the copyrighted material itself.
I've talked with Sound Choice's licensing group about this and using a PC to host a show and was told that as long as you can prove ownership of the original they will not press charges provided you don't make two copies for multiple rigs. In other words, if you own two karaoke rigs you need two sets of original discs.
Feels nice to get an 8125 for a present doesn't it? I got one myself for Christmas.
And my disk won't be leaving the house either.

BTW, the Digital Millenium Copyright Act really changed some of these things up but it's getting torn to shreds in court by groups like the EEF.

It's a long response, but shorter than most of my posts on this subject in the past....
