[MacDV] iMovie -> HandyCam export problem

[josh at joshrenaud.com]

Several months ago, I imported a bunch of old VHS video into iMovie on  
my PowerMac G4. I played the tapes off a recent Sony VCR through my  
Dazzle Hollywood firewire coverter. I had no problems bringing the  
video into iMovie.

I then edited the videos and included them on several DVDs (through iDVD).

Now, I'm finally getting around to archiving my digital video onto  
Hi-8 tapes (I use a Sony TRV-280 camcorder, which uses these tapes. We  
make master tapes of all our finished, edited video).

But I am having trouble with 2 of the VHS conversions. When I try to  
export them from iMovie to the camcorder, the camcorder pops up a  
message in the viewfinder saying it is copyrighted material and it  
can't be recorded. The camcorder then stops itself and won't record  
the stream. The Mac doesn't seem to realize anything is wrong and  
keeps playing the video, so I have to stop it manually.

One of the two conversions is a collage of photos set to music from  
1994. It was done by a professional company for my jr. high class, and  
it's possible it may have copy protection.

The other conversion is of a video that was shot a few years ago in  
Bolivia by my brother-in-law. I am not sure if it would have copy  
protection or not. Again, it's possible, but I'm thinking it unlikely.

These are the only two to have this problem. I have exported other  
conversions very easily to the Sony HandyCam

Anyone encounter this before?
