I have a bunch of movies ripped at 4000bps for my ATV via HandBrake. I have tried the iTunes method of converting them for the iPhone, but that takes forever on my 1.86Ghz C2D Mini. (I killed my first attempt when it ran all night and was only at the 1/2 way point.) I think I need to get them to ~1500bps to be compatible with the iPhone. Is there a faster method?
