找了好久 終於找到答案了
原來是 nero 6在做怪, windvr , nero 6 和 quicktime 同時裝就有問題了

"MSIPVS installs, but when I start the application I get an error message "WinDVR has caused a problem and needs to shutdown" "
hpkuo credits this to sizzle in his hints and tips thread, but I'll elaborate a little. The problem is caused by QuickTime codecs installed by Nero 6.3.1.15. It is unclear whether later versions of Nero were fixed, but earlier versions should be okay. "A "quick fix" is to rename the files "NeQTADec.ax" and "NeQTVDec.ax" in "C:\Program Files\Common Files\Ahead\DSFilter\"."
Another alternative suggestion is to uninstall the codecs from the registry. I found this solution in another forum:
Go to Start > Run (or press Windows key + R) and enter:

regsvr32 /u "C:\Program Files\Common Files\Ahead\DSFilter\NeQTADec.ax"
regsvr32 /u "C:\Program Files\Common Files\Ahead\DSFilter\NeQTVDec.ax"

The only consequence seems to be that Nero Vision can’t decode Apple Quick time format after this (something I can live with)

If you do require QuickTime codecs to be installed, there is the Quicktime alternative available from here: http://www.free-codecs.com/download...Alternative.htm . Or you could just use an earlier version of Nero.
