标题[请问] mp4出现讯号不良?
时间Tue Jul 6 15:46:34 2010
最近开启某个mp4影片时,会出现类似天线收讯不良的状况。
用media player classic(6.4.9.1)播放时会变成这样

但是用print screen却是一片黑

想说可能是转码器的问题,
改用万能的kmplayer(2.9.4.1436,免安装版)来试试,
结果就好像在没有开灯的房间摸黑一样:

可是用kmplayer内建的撷图功能却

我只安装了以前进板画面说的那几个基本的转码器和coreavc1500,
用Gspot分析

先不管这两个播放软体撷图的结果为何相反,
请问要怎样才能正常看影片呢?
附上从kmplayer抓下来的该影片相关资讯:
