I installed v7.5 the other day but after editing the config the menus would freeze. After a google I realised I would have to wait for the newer version to fix the problem. I have now installed v7.2 and it works ok-ish. It was freezing a bit while playing but updating the correct Usb2 fixed that... nearly.
I streamed district 9 last night and it froze about 2/3 away through. Soon got it back to the part where it had hung though.
Bring on the next version I say.
