I just found this
http://www.papajohn.org/MM2-Issues-CantSaveMovie.htmlI guess this is a common problem. It has some ideas to what to do to fix it. The first ones i am going to try is
"If your wmm2filt.dll isn't 'registered', the error message will pop up quickly when you start the rendering process... for either a WMV or DV-AVI type. This happens with MM2.1; I haven't tested it with MM2.0 (let me know if you check it). The Setup > MM2.1 page has more info about this and other issues you'll have if one or more of the DLLs are not registered.
When an external USB2 Drive is set to 'Optimize for quick removal' and you can't save a movie as a DV-AVI.
When I put an internal Western Digital disc drive into an external enclosure and connect it by USB2, one of the drive's properties (Start > right click My Computer > select the external drive > right click and go to its Properties > Hardware tab > select the external drive > Properties > Policies) is set to 'Optimize for quick removal' so I don't have to use the Safe Removal utility in XP before disconnecting it. The other option is 'Optimize for performance'... which enables write caching in Windows... and I need to use the Safe Removal utility.
Optimizing for quick removal lets me render movies as WMV files, and small (30 second) ones as DV-AVI, but I have to switch to 'Optimize for performance' to render a 5 minute movie to a DV-AVI file on the external drive.
When QDV.DLL isn't registered - a key file needed to save a movie as a DV-AVI type.
For some reason the codec needed to save a DV-AVI file isn't registered. Try registering it manually per this post:
11/26/04 ...try this magic line on your Start -> Run dialog: regsvr32 %windir%\system32\qdv.dll when you press OK it should result in a message: "DllRegisterSever succeeded in qdv.dll". Afterwards restart WMM and try saving the file as DV AVI again.
When the version of QASF.DLL isn't up-to-date - it's a key file needed to save a movie as a WMV type.
12/16/03... I then went hunting for QASF.DLL. I suggest if you're getting a SA MOVIE (error) you visit this link as your first port of call.. and download the file relevant to your OS. I can happily report my MM2 is working like a treat again. "
