I had given up on burning dual layer DVDs using DVD Architect Studio 3. However, I just received the new sony brochure and it says that the New! Vegas Movie Studio, which is the package I bought, now supports dual-layer burning. I upgraded it to build 68 and it is still not registering my dual-layer discs. I am using Verbatim DVD+R DL discs. So did I get my hopes up or is there a way to burn DL. In concern to my other post I do not have a mastering tab, probably because I have the studio version. Thanks for the help!!!!!!!!!!!!!!!!!
