Thanks! What would you recomend for a good AVI to DV-AVI converter?

Also, do you have any recomendations for a "downsizing" converter? ie, when I do a screen capture at 800 x 600 pixels (my closest option on Windows XP), is there a separate converter to downsize the AVI to NTSC 720 x 480?

Thanks again!

ps - I have some Adobe Encore AVI issues as well, but will save those for another time...
