我使用的是 Ubuntu 16.04。我安装了 Hauppauge Win TV-HVR-2200 MC 卡并执行以下操作（从帮助解决 ubuntu 13.04 上的 hauppauge wintv-hvr-2250 问题)：
我复制了这些文件
NXP7164-2010-03-10.1.fw v4l-saa7164-1.0.2-3.fw v4l-saa7164-1.0.3-3.fw到/lib/firmware
你可以从这里获取 http://www.steventoth.net/linux/hvr22xx/firmwares/
只需查看文件夹你就会找到它们。
重新启动然后它们就应该加载。
你可以用 dmesg | grep saa7164 检查
当我dmesg | grep saa7164在命令提示符下输入时，什么也没有得到。
我打开了 VLC，它显示 Hauppauge WinTV-HVR2200，但什么都没播放。
当我mplayer tv://在命令提示符下输入时，我得到：

mplayer 和 vlc 都识别 Hauppauge WinTV-HVR2200 卡，为什么什么都dmesg | grep saa7164没有显示？有谁能帮我吗？
