I bought Vegas Movie Studio HD with 5 DVD-R included in the package. However, do I have to purchase DVD Architect Studio to be able save my rendered movie to DVD? I did not see an option to save to DVD.
DVD Architect Studio is the program used to burn DVDs. It is included in the install disc or is a separate download if you bought the download version. I has to be installed separately from VMS.
You use the Make Movie function to render your video to a compatible file to use in DVDAS.
