Yeah, I definitely think the movies could be re-encoded with less and better compression. I'd probably re-sign up to MET just to get them too.
I think they're even shrunk down a little too, the resolution is usually 520x416 for her videos, which is not a traditional video resolution - should be at least 640x480 for pre-HD stuff.
That's what made me think that recent video that showed up might just be an old video they found kicking around in their files. The resolution wasn't HD.
It's a shame she hasn't done any more work for other sites. I often get the sense while watching her movies that she actually went a bit more explicit than what MET like to show and so they cut them quite heavily. She's a playful girl
