The xml file could be cached there - pull the power cord to the roku and plug it back in. - also make sure your app is loading the xml from S3 now, and that the xml file isn't in the zip. (just to be sure)...and make sure the file on S3 actually is different. Sometimes I have 2 or 3 copies of files and inadvertently uploaded the wrong one, so I end up checking everything before running a test/demo. 🙂
