does not display deleted videos

Hello

I have a great blog with thousands of posts and thousands of youtube videos embedded in the posts. I want to collect deleted youtube videos so I can delete posts that already have a deleted video.

I installed this plugin, but it collected live videos for me, not deleted ones. The 30-day limit is also very confusing. You would need to review all posts and show only posts in which the video has already been deleted without the 30-day limit.
The link to the videos is just copied into the text of the post
Please update Youtube not found to wp7.1
