I use Web-Site-Downloader (www.Web-Site-Downloader.com) to download websites for later browsing offline, especially for help files, although I have never put a "website" on a DVD until today. Today I tried out a product called Easy HTML Autorun Builder from www.easyhtools.com. VideoRedo uses their software. I got Easy HTML Autorun Builder personal license for free using TrialPay to try out Netflix, otherwise it would be about $30.
When you run the software, you are instructed to point to the location of the first HTML page in your project, which often times is index.html. The software then installs the necessary autorun files in the same directory as the index.html file or whatever file you indicated as the first page. You can then use ImgBurn to burn the "website" to a DVD using the UDF 1.02 file system option.
I haven't yet received my activation code for Easy HTML Autorun Builder. Hopefully that will happen within 24 hours.
