Something that has not been covered in this (exhaustive) thread:
Very few sponsors offer downloadable content due either to 2275 issues, or licence controls. Many of the ones that do, seem to offer tiny 640x40- either screen caps, or with the idea that they are making life easier for submitters.
Personally, I am hoping that these changes reflect positively on smaller programs (such as ours

) who seem to be more flexible with their affiliates, and often produce their own content and so have no licencing issues to worry about.
