XNA プロジェクトにビデオを読み込んで再生しました。唯一の問題は、縦に半分にカットされていることです。ビデオのサイズは 800x600 で、ゲームも 800x600 です。最初は誤って 640x480 バージョンのビデオをコンテンツに入れましたが、その後 800x600 に修正しました。ただし、1/2 の垂直方向は修正されませんでした。640x480 の xnb がまだそこにあり、ロードされているのではないかと思いました。私はそれを探してみて、関連していると思われるものはすべて削除しましたが、それもうまくいきませんでした. これは、ビデオの半分のスクリーンショットです。
これが私のコードです：

graphics.PreferredBackBufferWidth = WIDTH;
graphics.PreferredBackBufferHeight = HEIGHT;
graphics.ApplyChanges();
