Link to it and it will download to visitor's PC. The MPG will play in whatever media player they have as the default for the .mpg extension.
You'll want to copy the .vob to your own PC, rename it, then see if you can simply click it to see if it plays automatically. If not it may have some added stuff and you'll want to get a .vob to .mpg converter.
How different is this alternative from "streaming"? Pardon my ignorance lol. I'm concerned that downloading the entire file to the user's PC will consume too much bandwidth. Is there another way for the user to play the DVD file, without downloading it first? Thanks.
