Why is this so hard to understand?
When these television series were being broadcasted on television there was noi such thing as these shows being released to home video, let alone on DVD, which was unheared of. While the studios who release these shows have to pay the creators of the show, the actors and actresses who appeared on that show as well as the music artists who performed songs for that show as well as the distributor of that artist who releases their music on CD.
Those artists and the recording studios who release their music do have the right to be able to make money from their music appearing on that show and to share in the profits as well. This results in liscensing fees for that music to a new medium, home video or DVD. Often enough, when an artist creates or records music for a television series the rights, more appropriately enough, only extend to broadcast rights, not home video or DVD.
While most of us moan and complain about a particular series not being released and cry about it not being fair, it's also not fair if we expect these artists and songwriters to not able to get paid for their work when that music is transfered into a different medium, which they are entitled to.
This would be akin to someone downloading a movie, a television series or music off the internet for free. While studios cry foul when someone does download their material without paying for it so should those companies "pay" for that music if they intend to release it to DVD.
Even when new music is created for newer television shows, often enough, these studios only negotiate for broadcast rights but when it concerns a major artist sometimes they will negotiate for liscensing fees due to the fact that that show could be released to DVD.
Support the artist by telling these movie and television studios to start paying these music artists for their hard work and to pay those liscensing fees for those songs if they wish to release them to DVD.
It's not too much to ask of these studios ... isn't that right, Gord?
