Hi,
I noticed that MTV UK's website were still hosting a number of Amy videos, and with other artists I have found that they are generally an acceptable 480p. Most of Amy's videos that I looked at were all 360p, however 'In My Bed' claims to be 720p. It is definitely sharper than the YouTube version, although I do not know if it is true HD - I thought some may want to take a look at my rip here. Many thanks!
