我最近在我的盒子里安装了一张 skystar hd2 卡。我已经加载了驱动程序，一切似乎都很好，但我无法调整。
当我尝试运行 w_scan（来自 apt-get，w_scan 版本 20130331，为 DVB API 5.10 编译）时，我收到 srate 错误。具体来说：
# w_scan -fs -s S93W1 US -k > a.conf
w_scan version 20130331 (compiled for DVB API 5.10)
using settings for 93.1 west Galaxy 25

找不到为我的卡配置速率的方法。
当我运行 kaffeine 来调谐和扫描频道时（我将其配置为使用相同的卫星设置进行扫描）：

我不知道为什么前端会失败。

我在运行 Ubuntu 14.04.3 LTS 且内核为 3.19.0-25-generic 的电脑上安装了 skystar HD2。
我住在美国，所以我使用的是 Galaxy 25 Satellite
我编译了最新的 v4l-dvb 源并重新启动以加载其模块（按照说明进行操作这里到时间)、构建安装的dvb-apps 和 szap-s2。
更多诊断：
# ls /dev/dvb

我只是希望能够调谐和嗅探一些 DVB-S 频道，而无需在 Windows 机器上工作
