Animoto have just updated their app to allow you to download a high RES mpeg4 and ISO (DVD) file. It costs $5 but is well worth it.
Resolution is doubled so will play well on a monitor and even scales to plasma or LCD screens.
We are using it to produce slick video which we play on digital photo frames in our office reception areas.
Only grumble is they still add the animoto logo and google checkout or paypal accounts are difficult in corporate environments.
