Media problem...then again, it could be a media problem.
Sorry about that, seriously...
We really do need some details , such as the MID (media code) of your blank discs, etc., etc.
I see that you've posted the same question 3 times.
I also note that at least several members have inquired as to the media code of your blank media. Unfortunately, your only response was to ask the same question, yet again.
Please do not double (or triple) post; not only is it against forum rules (the ones you agreed to abide by when you joined), but it's frustrating for anyone trying to help or follow multiple and fragmented threads.
