The Nero that's being sold at "5 Dollar Software" is the "Nero Express 6" version. The Express version is the pared down version that comes bundled with the full version of Nero. This one and the hardware bundled versions are being sold all over Ebay for more money. There's nothing wrong with it. For most people it would be sufficient for their needs and especially at that price.
You can find Nero 6.6 (full version) on sale - for a limited time - at Best Buy's online store for $49.99 >

There were $20 and $30 rebates offered in addition to the sale price, but I believe these have expired. I dont know if this same deal is being offered in their stores. With the 6.6 version you can go online at Nero's site (Ahead Software) and download the latest build - that is the complete most up to date version of Nero 6.6.
Personally I don't use Nero. Theres too much bloatware.
If you have Nero installed in your computer and have lost the serial number - dont panic - its still in your registry files, or it should be, unless your registry files have become corrupted. Dont uninstall Nero until you first go to the Ahead Software site >
