Hi,  
  
I'm not that savvy a ppt user. I have to do a presentation which includes  
  
pps file and ppt files which were made by someone else.  
  
When I try to open any of them I get the message that"Quicktime and a DV/DVC  
  
Pro NTSC decompressor are needed to see this picture"  
  
I installed Quicktime but nothing has changed.  
  
Thank you very VERY much to all who respond.  
  
Cheers
