應該不算是修改
算是用匯出與匯入的方式

我試用過以下兩種方試,但都没有成功,
1.Open [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Media Center\Service\Video\Tuners]
Within that key is another key named DVR and another named something like {A799A800-A46D-11D0-A18C-00A02401DCD4}
It will look like this

-Tuners
-{A799A800-A46D-11D0-A18C-00A02401DCD4}
-{04CBCD6F-0EFE-4E52-9209-43B6AC9D4217}
+TuneRequest
+UserSettings
-{54B4E960-C8E5-42A2-AC64-98A586B7BEA2}
+TuneRequest
+UserSettings
+DVR

Export {04CBCD6F-0EFE-4E52-9209-43B6AC9D4217} it wont be named that but its the top one, save it to the desktop named top.reg
Export {54B4E960-C8E5-42A2-AC64-98A586B7BEA2} it wont be named that but its the bottom one, save it to the desktop named bottom.reg

Delete both of those keys and it will look like this.

-Tuners
-{A799A800-A46D-11D0-A18C-00A02401DCD4}
+DVR

Close Regedit and Open the device manager
Open sound, video and game controllers, Disable Your TV cards

Shut down, and install your new capture card, then restart. If your card is already installed Reboot anyway.

Start MCE, and go to settings > TV > Setup TV Signal
Run through the setup process for your tuner, and guide.
Make sure it works and is not stuttering.

Close MCE

Open Regedit, and you should see this.

Expand the keys make sure the keys are filled out.

Export the key {BAF147BF-2181-466D-96FE-48020D0861DD} save it as new card.
Restart Your computer now.

Open Device Manager
Open sound, video and game controllers, Enable Your TV cards

Import the Registry Entries you exported
Double click on both top.reg and bottom.reg and say yes to import them.
Reboot

Open Regedit, make sure your on these keys

+DVR

All off the keys should look alike. The settings within will be slightly different.
Close Regedit

RESTART one last time.

Start MCE
Start recording
Change the channel
Start recording
Change the channel
If that worked you now have 3 working tuners

2.算是修改Media regestry吧?
The values for RecordOrder / RecordPrefered / WatchOrder / WatchPrefered created during section 5 are:
Digital TV Antenna A 0 / ffffffff / 1 / 0
Digital TV Antenna B 1 / 0 / 0 / ffffffff

Digital Antenna A 0 / ffffffff / 2 / 0
Digital Antenna B 1 / 0 / 1 / 0
Digital Antenna C 2 / 0 / 0 / ffffffff

For 4 tuners enter/edit the values to the following:

Digital TV Antenna B 1 / 0 / 2 / 0
Digital TV Antenna C 2 / 0 / 1 / 0

希望大家給點意見吧................

某人說的
有圖有真相
剛剛抓圖的
趁熱趕緊看
感謝微軟技術社群的MVP親自面授
讓我可以一次錄三台
只可惜哈滴不夠大
主機板插槽不夠多，只能再安裝一塊 PCI-E tuner
要不就得犧牲掉其他兩個 PCI slots
這樣一來，一次就可以錄到 6 台
天啊！有這麼多好節目會同時出現在 6 個頻道嗎？

不哈拉了！
你用的電視卡單獨都可以在MCE裡看電視嗎？

如何做到啊
可以作個教學嗎

屌!!!!!
我的電視卡都可以單獨在MCE上執行没問題,我現在家裡只有裝兩張卡(如圖)
請問paclec大大是如何辦到的呢???
是我說的兩種方的其中一種嗎?
你所使用的TV tuner card是有包含dual tuner的嗎?(一張卡上有兩顆tuner),還是三張都是分開的?
要經過什麼樣的測驗才可以獲選Microsotf MVP呢?

我也好想知道怎樣的系統可以一次錄三台?
不然每次錄娛樂新聞都一定要錄到重播的!很討厭看到重播那兩個字!!
17:00~18:30 TVBS-G娛樂新聞
18:00~19:00 八大娛樂百分百
18:00~19:30 三立完全娛樂

感謝分享!!

如何做到啊
可以作個示範教學或資訊聯結嗎?
看了好生羨慕!
拜託! 拜託!
