I had a bunch of video files (.TODs - mpgv video, mpga audio) that were useless unless I converted them, so I did. 

Once I converted them, the "Date Created" and "Date Modified" were obviously changed, since new files were created from the old ones. Is there an easy way to move the Metadata for the dates from the old files to the new ones? The project I am doing is chronology-dependent, so being able to sort by date is essential. 

I would be willing to convert all the files again, if there was a way to retain the metadata. 

I'm on a Mac, with Mac OS X 10.6.2 (Snow Leopard). 
Any help would be really appreciated!
