Do the OEM versions of Nero leave out Nero Burning ROM full version, because I don't see it in the Start/All Programs/Nero subdirectory in Windows?
I'm afraid this is the only question of yours that I can even begin to address. My Nero OEM disk created a Nero folder with a number of sub-folders and icons in the Start menu, but doesn't seem to include the traditional "Nero Burning ROM" at all. Instead it includes a dumbed-down version called "Nero Express." That includes a button titled "Nero Burning ROM" which just sends you to the Nero website - i.e., it hits you up for an upgrade.
Your v.6.3 version may be considerably older, so things may work differently for you. You might try downloading the
Major Update Package 1 - maybe it will accept the serial number that came with your OEM CD.
Nero Express seems to burn CDs and DVDs quite well, but I have to admit I find the huge array of programs included with Nero pretty confusing. I can't tell which ones I actually can run and which ones are just going to beg for money. The upgrade messages in the program and on the website seemed to indicate that I'd be able to use all or most of the programs in the suite, but in fact, I'm only licensed to use some of the programs included on the OEM CD. Nero even tried to install BackItUp as a startup program, but it displayed a message on every boot to the effect that I wasn't licensed to run it at all. The video and media-player stuff will all install fine, but complain about patent restrictions and licensing issues if I try to use them.
