I just downloaded PodFlicks, and I think you missed the biggest feature of this program that does make it different from ALL the others... iTunes is not required.
One of my biggest disapointments with the video iPod when I first got it was the cumbersome way you have to get video on to it. If you purchase video from the iTunes store, it's seemless, but if you want to put your own video's on the iPod, it stinks! You need to first compress the video to an iPod friendly format (that's what all these programs do), then get it into iTunes and sync your iPod. Ever try to find where iTunes put's the file? In an Unknown Artist/Unkown Album file in your iTunes MUSIC folder. Really nice. So after you have a hundred or so videos, it's a pain to find them. And it stinks that you now have ten's of gigabytes of video data in your MUSIC folder. That really makes sense when there's a MOVIES folder right next to it!
As far as I can tell, PodFlicks allows you to go around iTunes and manage the videos on your iPod directly. I can convert and store the movies on a hard drive/folder I want, and put it on the iPod directly from within PodFlicks. This is really cool!
iTunes is great for managing your music, and does a pretty good job, but it seems that the video integration was a hack. So far, PodFlicks seems to address this nicely. My biggest complaint with this program is it seems to not allow batch processing unless I missed something. Hopefully this is coming soon.
