Quoting DJ Doena:

Quote:
The link I provided will open the Feedback hub and show you the issue I raised with Microsoft.

Nope. Doesn't work.
In Firefox that link just takes me to the Windows Insider web page.
In Edge it asks if I want to open the Feeback hub, and then says "Your account doesn't have access to this feedback".

Prerequisties (just checked out)
- using Windows 10
- having the Feedback-Hub App installed (the DJ Doenas link provides a link to the Microsoft store, if the app is missing) and
- having Feedback-Hub App logged into a valid Microsoft account
- using any Browser (tested with Edge, Internet Explorer and Firefox)
- allowing the browser to open the Feedback-Hub App

Just upgraded PC from Win 10 Ver 1903 ==> Ver 1909 (OS Build 18363.476) today.

Tested various DVDs, BDs and 4Ks with the following results:

4K = OK.
BD = OK.
DVD = same Disc IDs as Version 1809 and 1903.
