Here we are 2 months later and the problem with the Nowtv downloads remains. It's a good job I have the Leawo Bluray Creator to use as a backup otherwise I would have dozens of downloads that I couldn't put on disc

try going into settings - av codec - select disable all gpu codecs for encoding & decoding
restart dvdfab and retry blu-ray creator again and see if you still have lip sync issue.
