Just figured out how to do this. Really nice for offline watching and to save battery. All you need to do is get the YouTube channel url and use Subscribe YouTube podcast channel RSS feed as MP4, FLV or PSP video feed, convert YouTube channel into FLV RSS feed, subscribe to YouTube in iTunes, subscribe to YouTube feed in your favorite podcast application. Watch YouTube feed offline, extract f to get a Doggcatcher url that's compatible. For format, select MP4 (iTunes). I then email myself the URLs and copy and paste into Doggcatcher. I just tried it with IGN's channel and it works great!!
