Your DVD/Blu-ray/UHD player remote control
When a trailer starts playing just click Top Menu button on remote to take you to disc main menu to slip trailers/ads
If that don't work Just keep clicking next chapter button on remote to skip each trailer etc to get to disc main menu
Majority of discs trailers/ads can be skipped quickly using remote control
There is a only a tiny number of home media discs releases from some foreign labels when they can't be skipped
