[MacDV] Re: Can't save iMovie 3.03 Projects

[Carlton Kelly]

Peter,

Well that will certainly free up some disk space.... :-)

Thanks for the history lesson. I did choose UFS on purpose (I *like* 
case sensitivity), but in retrospect it was a poor choice. I guess I 
better buy some blank CDs.

Thanks again for the assistance.

Carl
