Video for flash question

Hi,
[font=Arial]Currently we have two video files, one is for windows media and is 98MB and the other is for realplayer and is 78MB. First off is this a realistic file size for the web in any delivery format? [/font]

[font=Arial] [/font]

[font=Arial]The video files were created by a third party vendor and are propriety for editing, but they have offered to render the file in Microsoft DV or Quicktime DV. Which format would be the best to import to Flash MX Professional 2004?[/font]

[font=Arial]Thanks for your help[/font]
