Comment:

 We use ob_gzhandler to handle the compression of output and that handles
 deciding if the client supports it.

 It looks like either feedburner is sending the wrong headers and is
 getting gzip encoded data it doesn't expect or you are double zipping your
 output (for example if apache is also configured to compress output) and
 that is confusing all clients except the browser.

 Looking at your current setup at www.willerwin.com which validates at
 feedburner so I assume has gzip turned off in WordPress you output is
 being gziped presumable by the webserver itself.
