Comment (by Jim Stichnoth <stichnot@…>):

 Attached is a patch that demonstrates a very crude "fix".  It modifies
 RingBuffer::ReadBufFree() such that the readahead thread never fills up
 the entire buffer, and so the OPT1 case is triggered whenever possible.
 With this patch in place, every one of my ISO videos will completely load
 up within 5 seconds, which is on a par with non-ISO startup speeds.

 I wonder if this direction would help with BD playback as well.
