OK I have a big problem that I hope someone can help me with. I've recently started to try to make animations and videos and all that. I have used a number of programs including Arcsoft VideoImpression, AVIEdit, Jasc Animation Shop, etc. I can't output to AVI or any other video format in any of them. Whenever I try to save as an AVI I get program lockups and errors and the outputted AVI files are 0 bytes in size and I can't delete them until after I exit the program. So is my system missing something that would enable to save AVIs?
