I have hundreds of AVI files which I'm converting to MP4. It is essential that the converted video files share the same date and time as the original

I've been using SUPER to good effect in the past but the most recent versions have proven to be extremely unstable. Installing older versions archived on this site has caused some serious problems after the introduction of some spyware... not good.

Anyway.... I'm looking for an alternative to SUPER, something that will batch process and maintain file date and time info, and preferably save the new file in the same location as the original.

Any suggestions?

Thanks
