I have all (almost all) of my movies ripped to Divx/Xvid as .avi files. What player is best suited to playing these? I tried the stock players & they didn't work. will Doubletwist play them? I really don't want to convert them over again. Also, coming from the iPhone, I loved the way it synched my podcasts - I see that people rally like Isyncr. Is that the best app to use? At this point, until I re-think my home media integration solution, I want to stay with iTunes.
