I have a lot of AVI files on the HDD from loading DV tapes that I want to edit. If I work on the avi files and save them after editing them (mostly reducing the lenght) and do this several time, is there a loss in qulaity. I would like to archive these edited files as I can not fit all the contents of my tapes on the HDD (over 20 Dv tapes) and have a 200gig HDD.

Thanks
