problems burning NRG files but not what you think

My CD-RW is not capable of burning multisession games and for a quite a while now i've been able to successfully convert files from the CDI format to NRG format using that CDI2NERO program. Its been a blessing as i've been able to burn lots of games but here is my problem. There are some games out there that have been ripped but the music files are in MP3 format, so according to these groups you have to run unpack.exe which extracts these files into WAV format.


Then you have to run inject.exe and it puts the music files back into the CDI file. I do this and then i convert the CDI file into a NRG file to be burned with NERO.

Once i try and burn it with NERO, it gives me an error message that says headers have been changed and it quits on me. I was wondering if anybody else has had this problem and if so what was your way around this. I have this same problem with any game that i need to unpack and inject. All other games that don't require these steps i've been able to burn.

I know this was long-winded but i wanted to make sure people understand the problem and I haven't seen any other posts on this. Any help is deeply appreciated.
