error trying to create an Audio CD with nero 7

[Cruiser]

Hi
I'm trying to burn a CD with Nero 7. i've burned tons of discs in the past from mp3 files.
but now with some of my mp3's i'm getting this error when i try to add them to the window for burning:


'One or more files could not be added to a compilation.

It may be possible, that the files can be added, if a dedicated plug-in is installed.'


what plug in is this i need?
there is nothing different about the mp3. it's not protected. is there anything else about the mp3 i should look for?

many thanks

Could be they're MP3pro or more likely, they were ripped from a DVD. Then they're 48kHz instead of 44.1, a no-go for an audio CD. Open them in Winamp and check their properties. You can use the Nero wave editor to resample to 44.1 kHz.

they are actually 44.1khz VBR MP3's
got that info from sony sound forge
like you say it may be best to resample them
thanks
