Netflix problem in Safari 8.0.6

Hi, I've just had a long online chat with the Netflix support team as I can'r run any Netflix movies on my iMac. I am currently running Safari 8.0.6 with Yosemite 10.10.3. They are telling me that there is a an update to Safari that fixes this. However, I cannot see any Safari updates. Has anyone seen a 8.0.7 update that resolves a DMR issue?
