[請問] mp4出現收訊不良?
最近開啟某個mp4影片時，會出現類似天線收訊不良的狀況。
用media player classic(6.4.9.1)播放時會變成這樣

但是用print screen卻是一片黑

想說可能是轉碼器的問題，
改用萬能的kmplayer(2.9.4.1436，免安裝版)來試試，
結果就好像在沒有開燈的房間摸黑一樣：

可是用kmplayer內建的擷圖功能卻

我只安裝了以前進板畫面說的那幾個基本的轉碼器和coreavc1500，
用Gspot分析 http://img810.imageshack.us/img810/836/20100706154029.jpg
先不管這兩個播放軟體擷圖的結果為何相反，
請問要怎樣才能正常看影片呢？
附上從kmplayer抓下來的該影片相關資訊：
