房間的兩台電腦xp,win2000
都搜尋不到訊號(搭配電風扇也是無訊號)

拿台NB(xp)來試,有搜尋到訊號(搭配電風扇,訊號也近滿格)

同樣的驅動程式,同樣的地點,
NB行,兩台主機卻不行

這是什麼道理??
難道是主機干擾源太強??


因為驅動程式收到的Bandwidth參數不正確.
這是已知Windows 2000, Windows XP, Windows XP SP1 的 BUG.
Windows XP SP2, Windows MCE2005 Rollup 2 之後才解決.
當然Windows Vista 沒有這個問題.

所以在Windows 2000下, 你需要一個特別修改的驅動程式(Bandwidth參數固定成6MHz).

For example,

If you want to run WinFast DTV on Windows 2000 SP4:

Europe (UK, France, Germany, ...etc.)
Step 1 : Download the Microsoft GDIPLUS.DLL for Windows 2000 from the following link:
http://www.microsoft.com/downloads/deta … layLang=en
Step 2 : Run the downloaded gdiplus_dnld.exe and unzip to the folder of WinFast DTV -
C:Program FilesWinFastWFDTV

Australia :
Step 1 :The driver 4.0.107.3204 must be used in Australia.
ftp://ftp.leadtek.com.tw/tv_tuner/DTV10 … 0_WHQL.zip
Step 2 : The Leadtek_DVBT_Australia.REG is needed for Australia (7MHz).

Step 3 : Download the Microsoft GDIPLUS.DLL for Windows 2000 from the following link:
http://www.microsoft.com/downloads/deta … layLang=en
Step 4 : Run the downloaded gdiplus_dnld.exe and unzip to the folder of WinFast DTV -
C:Program FilesWinFastWFDTV

Taiwan :
Step 1 :The driver 4.0.107.3204 must be used in Taiwan.
ftp://ftp.leadtek.com.tw/tv_tuner/DTV10 … 0_WHQL.zip
Step 2 : The Leadtek_DVBT_Taiwan.REG is needed for Taiwan (6MHz).
http://tw1965.myweb.hinet.net/Leadtek_DVBT_Taiwan.reg
Step 3 : Download the Microsoft GDIPLUS.DLL for Windows 2000 from the following link:
http://www.microsoft.com/downloads/deta … layLang=en
Step 4 : Run the downloaded gdiplus_dnld.exe and unzip to the folder of WinFast DTV -
C:Program FilesWinFastWFDTV


PS : The TimeShifting does NOT work on Windows 2000 SP4, because the Microsoft SBE does not exist.
The Microsoft GDIPLUS.DLL is included in the latest WinFast DTV which you can download it from Leadtek website or my website :
http://tw1965.myweb.hinet.net/WinFastPVR2.htm
http://tw1965.myweb.hinet.net/WinFastDTV.htm

PS: It is Microsoft's bug, the DVB-T bandwidth is not passed to BDA driver.
And this bug is fixed since Windows XP SP2.
And the default bandwidth of driver default is 7MHz for VHF (below 300MHz) channels,
8MHz for UHF (above 300MHz) channels.
And this default bandwidth setting works for the Europe (UK, France, Germany, ...etc.) DVB-T.
But, the bandwidth is 7MHz for both VHF and UHF channels in Australia.
the bandwidth is 6MHz for both VHF and UHF channels in Taiwan.
So, you need special driver to work on Windows 2000 in Australia and Taiwan.
