你是使用Microsoft Media Center ?
Microsoft Media Center 不支援"臺灣" DVB-T.
Microsoft Media Center 的Analog TV 需要 MPEG-2 Encoder(Software or Hardware),你沒有裝Microsoft Media Center 認識的Software MPEG-2 Encoder.

COMPRO PVR, WinFast PVR, WinFast DTV 和其它PVR/DTV 軟體應該都可以正常使用.
如果不正常, 請用Task Manager 結束執行中的 ehRecvr.exe.
(WinFast Wizard 會自動結束執行中的 ehRecvr.exe)

我安裝了Microsoft Media Center 2005
我現在測試用cable看
但是有聲無影...裝了NVIDIA_DVD_Decoder_v1.00.58
一樣有聲無影 且顯示loss of signal ??

不會吧 不支援台灣DVB-T ??不是出了繁體版了??
雖然我是裝英文的...

Microsoft Media Center 需要 MPEG-2 Encoder和 MPEG-2 Decoder.
你只裝MPEG-2 Decoder, 沒有MPEG-2 Encoder.

你可以用 Microsoft MPEG-2 Decoder Check Utility查看MPEG-2 Decoder是否安裝.
如果裝多個 MPEG-2 Decoder (CyberLink, InterVideo. NVIDIA, ...),
可以用Microsoft MPEG-2 Decoder Check Utility來選擇使用那一個.

一定要裝Windows XP Media Center Edition 2005 Patch KB873369 (Update Rollup 1 for Windows XP Media Center Edition 2005):
可以使用Windows Update 或下載，下載網頁如下:
http://www.microsoft.com/downloads/...&displaylang=en

這個Patch 支援USA ATSC HDTV, 還修正很多問題:This update for Microsoft Windows XP Media Center Edition 2005 enhances the stability and performance of Media Center 2005 and also resolves the following issues:
• Under certain circumstances, when you watch Live or Recorded TV, the audio and video may not be synchronized correctly.
• When you press the Live TV button on the remote while you are watching Recorded TV, a video, or a DVD, a black screen or an error may sometimes occur.
• If you try to watch Live TV immediately after you complete the First Run Wizard in Media Center, a video error may occur.
• When you use a Media Center Extender to try to view expired media content, the extender device may stop working correctly until it is restarted. If you install this update and then try to view expired media content on the extender device, an error message will occur, but the extender device will continue to work correctly.
• After you install this update, the response time for changing or for scanning FM radio stations is much faster.
• After you install this update, the performance for certain PAL TV playback hardware configurations is much improved.
• When you try to change channels in the Program Guide while both NTSC (National Television Standard for Communications) tuner streams are being used by Media Center, an error may occur or Media Center may stop responding. When this problem occurs, you must restart Media Center. For example, this problem may occur if you try to change channels in the Program Guide while two programs are being recorded. This problem may also occur when one program is being recorded and another program is being sent to another location by using a Media Center Extender.

還是搞不定耶！
我重裝了一次MCE
這次改裝簡體版
但問題依舊
我看T300算了.應該是不能用MCE了
MCE不是都支援硬壓電視卡 而T300是軟壓的卡
看來不能對T300太過要求 畢竟不是同等級的東西
寫信問COMPRO也沒回
算了....還是謝謝TW1965兄了
