[MacDV] Video camera

[Robert Green]

I didn't see anything on this in the archives so here is my question.  
I have a Canon mini dv camcorder that I use outside quite often and  
consequently have dust problems on the recording head. It is now past  
repair and I want to replace it. The hard drive cameras sound like a  
good idea but they are not compatible with imovie as they record in  
mpeg2 format. Are there any hard drive cameras that  are compatible  
with imovie or is there a simple way to convert mpeg2 to dv or  
whatever format imovie can use?
