Is HBO Max and Cinemax the same thing?
No. Like HBO Now and HBO Go, which are alternative streaming services from HBO, the feeds of HBO’s cable channels or any Cinemax content are not included with HBO Max.
Most of the merged library’s movies will be available on both platforms in separate windows even though Cinemax and the linear HBO channel share content for movies; nevertheless, these movies may not always be accessible simultaneously on HBO Max and Cinemax.
