Svanur, I moved your discussion from the French forum to the premiere pro one. Please give more info as your platform and the version of PP that you are using and the error message that you get...
Make it real DV, 720 x 576i/25 and 48 KHz 16 bit stereo before trying to import. The specs you gave are not DV.
I agree with Harm. The specs. do not match up correctly. Where did those AVI files come from?
I assume that you are working in PAL-land (and not NTSC-land). Is that correct?
What platform are you working on, Mac, or PC?
When you attempt to Import those AVI files, what is the exact error message that you are getting?
