I started using Handbrake this week to convert my Blu-rays over to smaller files to use to stream over my home network. However, I have been noticing an issue when it seems like the file becomes too large. I am using just some basic settings with Handbrake, keep the files as 1080p. An example of the problem I am having is with Batman Begins. When I set it to use constant bit rate at 70%, it create a 10 gig file. When I try to add it to iTunes it fails. When I try to play it with VLC, nothing happen. However, when I set Handbrake to 60%, file works fine. So is there some type of limit that MP4 movie files can be? I am also running OS X so maybe it's an OS X issue?
