It appears to be working fine on Thunderbolt with CM7.
Interestingly enough, when I installed and launched, I saw the movies section. However, I just rebooted my phone and relaunched the market. Strangely I was asked again to agree to the terms (despite already doing that after first installing the new market) and now see that there is no Movies section nor any reference to Movies. Anyone else experience this? Looks like the root discrimination with Movies is in full effect.
