I hit this problem a Couple of days ago and now after some testing I believe it might be a bug. I have notice while using .Net 2003 with the Tlbimp generated DLL that when I set the Write Buffer in the Nero Object to anything other then what it defaults to that, during burning, the NeroCOM API gets stuck in a infinite loop while trying to fill the buffer. I was wondering if this is a known issue (my search on Write buffer was empty) and if there is a workaround. If it isn't has anyone else here set the write buffer without a problem (if you have could you provide code as a example)?
P.S. I am using both the latest SDK and Nero Version.
