Hi Heidi,
I had the same experience many years ago the first time I attempted to make a DVD – you can’t simply burn media to a DVD disc and have the DVD player see it as a “Video DVD”. It MUST be Authored, using Adobe Encore or similar software. This compiles everything and you end up with a “VIDEO_TS” folder on the disc, with .vob files and other stuff inside. Insert any DVD into a computer drive and OPEN it and see.
And even knowing that, one cannot “copy” the VIDEO_TS folder from an existing DVD to their hard drive, and then BURN that to a DVD and expect that to work either. It will just be a “Data” disc and not an official DVD – the files must be written a specific way to the disc, some sort of pointer set that tells the disc reader “The is a VIDEO DVD”, rather than a DATA disc.
If you have Adobe CC, you will be able to download and use Encore CS6 – https://helpx.adobe.com/encore/kb/encore-cs6-installed-cc.html
