My notes on this - may be of help.
Error -50   paramErr  Error in user parameter list
Can there be any external hard disks - if so How are it/they formatted ? 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? How much ?
• in what format ? .jpg, .bmp, .tif, else ?
• from where/what format ? iTunes, .avi, .mp3, .aiff, else ?
The "" file
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..
