As far as I know, PowerDVD has no affiliation with Interactual Player.
I have been using PowerDVD for years and it has never installed or prompted for the installation of Interactual Player. It is doubtful if uninstalling PowerDVD would rectify the issue.
Interactual Player is seperate software that is usually bundled with some DVDs and will always prompt the user for authorization to install whenever the DVD is inserted. It is always a user authorized installation.
