Oprea

Perhaps download the professional version demo.

The preview browser does not (by default) play movie files.

If the Evo demo supports export to HD (I doubt it) you could export and the open the site from your default browser by double clicking on the Index file. Pro has the option of selecting your default browser at preview.

The necessary addons can be installed in the preview browser, but I doubt the effort is worth it if you have not committed to purchasing.

Why not purchase and in the unlikely event you are not pleased, request a refund within 30 days?
