new sponsor Q- urls on promo movies?

[Tyranni]

I have a new affiliate program, and I offer mostly short movie clips for MGP promotion.. would it put off affilates if the clips had my url at the end of the clip, or rolling at the bottom for a few seconds? The reason for this being that if the clips get passed around the net at least it can come back to the source. If the url is not acceptable for affilates, would any promo or informational text be a put off? Normally I would just do things as I like, but the affiliate program is new and I don't want to chase anyone away right now.
