Hello, Nicole and welcome to the Prism Forum. I am pretty new to Prism myself. I only use it occasionally, so I stand to be corrected by those more knowledgeable than me. From what I can understand, you can't directly convert from, say, .mpeg2 to .vob. What you can do is tell Prism to burn a DVD. It will create the .vob files on the DVD that you can then copy to whatever other media you want. You can always use rewriteable DVDs if your final destination is not a DVD, though in most cases, that is why .vob files are created in the first place. Hope this helps. Have a great day. Regards, -Phil
