ok i have about 400 .mp4 video files. and about 90% of them are ipod compatible because i used isquint for them. now the other 10% of them are older dvd rips. back in the day where handbrake diddnt have the "insert ipod atom" option. so i have a couple scattered movies that are not ipod compatible. here are my questions.

1. how can insert the ipod atom to all of my files?

2. how can i view my files in the fashion of "sort by video codec"

either i want to insert ipod atom to all to make them ipod compatible or i want to quickly identify the problem files and re-rip them.

any ideas?
