A WebDVD is not one file but several, like its own little web site.
In fact, it needs to be the only thing on a web page in order to work.
So, if I understand what you're asking, no, you can not allow your clients to download a WebDVD file and then view it on their computer.
Thanks for your reply Steve!
Do you have any thoughts one how to do a custom Disc Menu?
There are many considerations, when creating "custom" DVD/BD Menu Sets for PrE. Do you have Photoshop, the big-brother to Photoshop Elements?
I do have Photoshop CS4. Are there menu sets there or are you saying I would make my own design and insert it into PrE?
If you have Photoshop, then you can do almost anything that you want.
The reason that I asked is that Photoshop can CREATE Layer Sets (basically the Buttons), where PS-Elements can ONLY edit those.
You might want to look at the link in this ARTICLE, for some tips for creating you own Menu Sets.
