Newbie: Didn't import into iMovie HD

I found a lot of clips I liked and since I'm not an expert on video, I downloaded one clip to make it would work. It was an HD 1080 (1920x1080). I downloaded it into my Mac successfully.

Next, to get the clip into the Mac iMovie HD, I simply need to drag it into the open application.

But...Bummer. It didn't work! The error message said:

"Error during Import.
The file could not be imported: Unknown Error"

Anyone know how I can import this clip into iMovie?

Thanks.

I fixed the problem by changing the name of the file. Sometimes the simplest solution is the answer.

Good to hear you found the solution. And I thought only Win* computers had that kind of problems. ;-)

Welcome and sure glad you have chosen P5 as your place to buy. If ya don't mind telling us about the clips you chose, and how you plan on using them. It's always a great motivator to the artists and videographers here when we can see out work being used.

Thanks and good luck.
