A few questions about Sony Vegas Movie Studio 8

Hi just a few questions about Sony Vegas Movie Studio 8

1.Can I import and burn directly to DVD avi files encoded with DivX?

2.If I go out and buy the program retail (like from best buy, circuit city, etc...)can I just install it from the DVD even without internet access? I'm asking because I was going to try the free trial from the website but it said I needed to download additional software (Visual C++ and Microsoft Framework I think)

To Sum um the last question does the program DVD come with everyting you need to install it without having to download additional software.

Also please don't bother pointing out this post is in other fourm areas I know I just tend to get faster responses when I post it in other areas relating to my questions.
