I recently assembled a new machine and installed Windows 7. I equipped it with an ASUS CD and DVD burner which came with Nero 9. My old machine had Winows XP and USED Nero 7 which worked quite WELL as I burn a lot of music CDs and DVDs. Problem, all of the CDs that I burn using Nero 9 will not play in one of my CD players. They will play in my wifes radio/CD player and my computer but not in my commercial Karaoke. Both Nero 7 and Nero 9 put out the music in CDA format regardless of whether I "add" them as WMA or Wav format products.
I am thinking of reloading Nero 7 into my new machine but the CD states that "Bundle with hardware only not for resale". Questions:
1) Does anyone know why I am having this problem?
2) Does it have anything to do with finalizing the CD?
3) Do I need to buy more plug-ins?
4) Is it legal for me to use Nero 7 in my new machine with the new burner? I can remove the program from the old machine but I want to keep the new hardware in the new machine.

I am stumped. Thanks for reading this. Appreciate any help you can give.. JIMOthers have had problems similar to what you report. But the problem is not limited to the Nero software. This can happen even with other brands of CD and DVD burning software.
Here are some things to check for; quality of the media your are using and even the type of media you use. The CD RW media can fail more often and does not work in some consumer CD players. And yes, this CD must be finalized for use in a common consumer type CD player.
Also, you may want to check what is the default writing speed on your PROGRAMS. A good burner and good media should have no trouble with 16 X. But you may have to drop down to a lower burn speed to see if that helps any.
As for the Nero copyright infringement question, Nero will allow you to use almost any version of their software for least 30 days on a trial basis. You are not violating the copyright if you only use it for 30 days.

If at any time you have purchased the full version of Nero, you should be entitled to use any other version that's lower down on the list. Normally, you would only install one copy of Nero on one of your computers.
But if you're the only person that uses your computer's, and you never use them at the same time, or if you never use Nero at the same time on two computers, you would not be violating the copyright law by having a backup installation on one of your computers.

And I don't think you would have any reason to be using Nero on two machines at the same time and burning CDs at the same time, unless you're doing some kind of commercial work. In which case, if you were a commercial user, you would probably have better equipment and you would have all the licenses you need to MAKE as many copies of anything you need if you're in the business of making copies legally for other commercial entities.
In the USA, having two installations of software by one individual in his own home or office where he is the only user is not a violation of copyright law. Unless he uses both at the same time.

Thank you. That clears up some other questions that I have been pondering. As to the burners I think I have the answer, the burners themselves are different. After I read your response, I uninstalled Nero 9 then did a "drag and drop" on a file consisting of both .wav files and .wma files, in both machines, also using two different CD media. (four discs total). The two that I burned on my old machine worked fine in my Karaoke while the two that I burned on the new machine did not...although they all work great in other CD players. The tolerance combination of my Karaoke machine and my new burner must be just slightly out of bounds with each other..
I think that it is too late to get a refund or return from NewEgg, assuming they would even consider a refund under the circumstances, so I will just swap burners and change it LATER....

Thank you very much for your help. I really appreciate it. JIMYou are very welcome.
