Not being a Windows person, it's maybe a bit out of my league. Have a look at this website (click link) & its adjoining forum. I suspect they will be better able to solve your problem. Alternatively & this might be a bit off the mark but the following link to another forum which 'might' have a subsection to also discuss these types of problems: Forum 2. Hope this helps.

It depends upon the format the files are in as to whether your burn app(s) can handle them. Some can handle avi & mpeg1. Some might be able to handle other mpeg formats but u might have to purchase xtra codecs for them. The files u dwnlded 'might' need to be converted 1st. Particularly if it's a vcd you're trying to create.
