Hi,

I am using NERO 6.3 version. I am using VC++ as the client to communicate with NEROCOM. I was able to burn Audio CD. but I am facing problem for data CD. I am using BurnFreestyleCD () to make a Data CD. Here are the log messages.....

Reading Directories
Creating Directories
Checking Discs
Writing to cache
caching of files started
caching of files completed
writing to Disc
Burn progress started @ 4x 600 kb/s
Writing tracks
Writing Lead in and Lead out
Write Error
could not perform End track


I came to know that "Write Error" is posted if there is a media mismatch. but i am able to make a data CD using Nero Application( which is provided when we buy the software). So I feel that there is some other problem...Please see the piece of Code and let me know where I am going wrong...
