According to a post at the Photobucket blog, MySpace has made changes to prevent Photobucket users from posting their videos and remixes to MySpace pages:

This action by MySpace means that all of the videos and remixes you created will no longer show up on your MySpace profile, blog and comments section. More specifically, if you attempt to add new videos or remixes to your profile, they will be removed.We are not happy about this and we‚Äôre pretty sure you‚Äôre not happy either. We appreciate that you have invested hundreds of thousands of hours using the editing, remixing and management tools and features available only on Photobucket. In particular, you’ve all been really embracing videos at Photobucket — to the tune of 50,000 video uploads a day, which is great. Rest assured that your content is being kept safe in your Photubucket album even though it may disappear from your MySpace pages.

We believe that by limiting your ability to personalize your pages with content from any source, MySpace is contradicting the very belief of personal and social media. MySpace became successful because of the creativity of you, its users, and because it offered a forum for self-expression. By severely restricting this freedom, MySpace is showing that it considers you as a commodity which it can treat as it sees fit.

The change by MySpace highlights the tradeoffs of relying on a closed social networking site for hosting. While the site offers great opportunities for exposure, they control what you do…..and how you do it.
