Here's what you neeed:

    + /iso
    + /iso/1.5.*
    + /iso/1.5.*/i386*
    - /iso/1.5.*/*
    - /iso/*
    - /*

In order to understand why you need to realize that the rsync algorithm
recurses down into each directory and applies each pattern in order and
stops when it finds a match, so if you don't explicitly include the parent
directories they get excluded by the exclude wildcard and rsync never
descends down into the directory.  Note that "/*" only excludes things at
the top level, that's why I had to explicitly exclude things at the next
two levels too.  A simplification is this:

    + /iso
    + /iso/1.5.*
    + /iso/1.5.*/i386*
    - *

because if you don't have the slash preceding the exclude "*" it applies at
all levels.

The most recent snapshots of the development version of rsync will give you
more helpful information if you use -vv, but it's not yet in any released
version.  The patch is at
