Try this: right click on the folder that you want to zip., lets say it is in the folder roku_sdk_v30/examples/source/simplevideoplayer Right mouse-click on the simplevideoplayer folder, If on a mac, select "compress" or "archive" if on a pc, select Send To: Compressed (zipped) folder. Then try uploading that folder to your roku, and packaging it.
If this issue still happens, then you need to make sure that when you zip the file up your are excluding hidden and system files, like thumbs.db for example, or any mac system files, files which may not be visible to you, but are there. (there are ways to show hidden/system files on windows and mac machines).
