With the last 3 patch on the Roku 4k ultra. When you open the Vudu app and select a movie from the start it plays normally. However if you move to another chapter there is a 50 50 chance sound will be out of sync. If you fast forward or rewind the sound will be 90 pct chance it is out of sync. It happened on the same patch were youtube started to receive hdcp 20 errors. Figured I would pass it on, haven't noticed it yet on the 4k streaming stick Roku
Getting it on all VUDU with and without commercials. Using both ROKU 4K wired connection and ROKU+ on WiFi. Did notice that while the movie sound is out of sync, the commercials sound are fine. After weeks of giving up on various VUDU movies, I finally gave up and deleted VUDU from both ROKUs.
