"Microsoft Media Center 不支援" 臺灣 " DVB-T" 這句話基本上是錯的

應該修正為, DVB-T TV 卡的廠商所推出的 BDA 驅動程式的 MCE_FreqTranslate 要能夠支援台灣 DVB-T 所使用的頻譜波段

這是某一家電視卡製造商的 BDA 驅動程式的 Release Notes

至於這是哪一家做的, 看名子就知道了...

具備專業能力的製造商, 不僅有自有硬體的研發能力, 研發團隊對於軟體的廣泛支援度跟穩定度以及開發能力更是重要

Twinhan BDA driver for DVB-S/-T/-C/ATSC


For differnet applications, please install with the corresponding INF files.
1. For MCE2005 & DVB-T in Australia, please install with "THBDA_MCE_AU.inf" in folder \THBDA_MCE_AU.
2. For MCE2005 & DVB-T in UK(VHF/UHF:8MHz, like UK), please install with "UDTT2BDA_MCE_UK.inf".
3. For MCE2005 & DVB-T in Europe(VHF:7/UHF:8MHz, like Germany), please install with "UDTT2BDA_MCE_EU.inf".
4. For MCE2005 & DVB-T in Taiwan, please install with "THBDA_MCE_TW.inf" in folder \THBDA_MCE_TW.
5. For non-MCE but BDA based application (like ShowShift) or DVB-S/DVB-C/ATSC, please install with "THBDA.inf".

To install DVB-S/ATSC, please refer to THBDADriverNote.txt for proper settings in inf file.

A BDA utility (THBDAConsole.exe) is included. With this utility, users may change the BDA default settings after
driver installed.

Usage for THBDAConsole.exe:
If THBDAConsole.exe is launched with the parameter -S, it's started in minimized mode on the task bar.

For Windows MediaCenter (MCE2005) DVB-T users,
If the option "Auto setting by country (for MCE)" is enabled, the driver settings will be changed for
MCE2005 accroding to the location of Windows XP installation.
The location setting can be changed in "Control Panel" -> "Regional & Language options" -> "Location".
To enable this option, users should make sure if the location is set correctly.
By default, the option "Auto setting by country (for MCE)" is enabled.

The option "ShiftFreqScan" determines if off center frequency scan(+-167KHz) will be done or not in MCE2005.
For each DVB-T channel MUX, MCE will scan triple times, the central frequency F, F-167Khz, then F+167Khz.
Our tuner's frequncy range tolerance is larger than +-167KHz, so there will be triple programs found.
Disabling this option can improve channel scan speed and eliminate the duplicated programs found.

For non-MCE BDA applications, like Showshifter, PowerCinema 4, WinDVR6...,
The option "Auto setting by country (for MCE)" "MUST" be un-checked.
Two other options "MCE_FreqTranslate" & "FixedBandwidth" "MUST" be set to "None".

Known issues with MCE2005
1. MCE2005 DVB does not support AC3 audio. (only ATSC AC3 is supported)

to 1920x1080i or 1440x1080i)
3. MCE2005 does not include any MPEG2 decoder, so you should install a MPEG2
decoder first, either IVI, Cyberlink, Elecard, or NvDVD.
4. Not all VGA cards can support MCE2005 well, the only VGA card we test ok
is Nvidea GeForce4 MX440 & MX4000.
