Good programs for image sequencing dng's?

[Gwydien]

I don't really want to spend $500+ on software but right now i have to spend hours converting the dng's to png's using Photoshop elements 10.  Only then can i use virtual dub to make an image sequence because it doesn't support dng's.  Is there a better way around this without spending huge money?  I am willing to spend a certain amount.  And ive tried quicktime pro and it doesn't seem to work; it messes up the video completely. 

Thanks

If you work on a Mac, try Quicktime 7.0. Try to do a google search, or check Nofilmschool.com, there is an article there about converting DNG Files to fully compatible ProRes movie file.
