I pulled the APK from my Nexus One which is one of the 4 supported phones able to run the legit Netflix app released today...
BUT, I believe the APK is available on XDA.
As for the Build.prop...
Its located in /system (Yep, a system file so CAUTION!!!)
MAKE A COPY AND KEEP IT SAFE!!!!!
Edit with root explorer
Change the following...
ro.product.model=VM670
ro.product.brand=VirginMobile
ro.product.name=aosp.thunderc
ro.product.device=thunderc
ro.product.board=thunderc
to
ro.product.model=Nexus One
ro.product.brand=google
ro.product.name=passion
ro.product.device=passion
ro.product.board=mahimahi
a couple spaces down you'll see
ro.product.manufacturer=LGE
change to
ro.product.manufacturer=HTC
save and reboot.
I REPEAT!!!!! KEEP THE ORIGINAL Build.Prop.
Here is the vid of Netflix streaming...
YouTube - Netflix streaming on an Optimus V.
