I am getting ERROR -50 when trying to export my 3 minute video. PLEASE HELP! I have 11G on hard drive, but comp seems to run slow on start up.... can I export or copy it in some other fashion? Desperately need help. THANK YOU!

Question

Oops, Looks like I said most of what I wanted to in my title. Sorry ppl, my first time here.
So, my vid won't export.  And I need it soon.  I'm kind of in a panic.  First time I've had this problem.  The music from iTunes also aliases at times, but I can get it to play without that problem on occasion.  (What causes that?  That does happen with frequency, but then goes away at times.)
BUT, is there ANY WAY TO EXPORT or move a copy of the video somewhere else?  (How, if so?) 
And what does ERROR -50 mean?
Also, please know I am fairly computer illiterate, so if one could speak in the simplest terms possible, I would really dig that.
THANK YOU SO MUCH!!

Hi
This is an easy Q: to set - but there is no simple and plain answer only a lot of more or less plausibly suggestions.
Error -50 = paramErr  Error in user parameter list
Can there be any external hard disks - if so How is/are it/they formatted ?
If so it Must be Mac OS Extended (hfs) if used for Video.
UNIX/DOS/FAT32/Mac OS Exchange - works for most but not for VIDEO.
What this means in Your situation is above me.
• free space on internal boot hard disk 11Gb is on the limit to work when You select Export and might be it.
Video used - there are several video formats/codecs and iMovie can not use all of them, they evolve to fast.
• So try to find out by opening a raw video in QuickTime-player and then open Inspector (cmd+I) and read
Video Format/Codec: nnnnnnnn
What does it read ?
Pictures
• in what format ? .jpg, .bmp, .tif, else ?
Audio
• from where/what format ? iTunes, .avi, .mp3, .aiff, else ?
I convert all audio to .aiff - in iTunes I burn out as an Audio-CD .aiff (not .mp3) and use the files on this in my movie projects.
Some times it's needed to trash the "com.apple.iMovie.plist" file in You USER-Library/Preferences (not Library on Root level (when opening Macintosh HD) - but the one in Your home folder.
Many users has not observed that there are TWO libraries.
• Library - at root level
• Library - in user/account folder - THIS IS THE ONE to look into

I fixed the problem.. but it was very, very strange. I had a very long section for credits and set the line spacing to 1.0.. for some reason this caused it. I removed it, and it worked fine. I put it back, and I couldn't preview or play the video.
I don't know why that could cause that big of a problem, but it did..
