Hi

New user here, noob question.

I started to download an avi last night, and I did a preview but all I could was sound, and some very occasioanal glipses of video but mainly the video was greyed out.

When I came down this morning the avi had completed and it plays fine, althought it's not the avi it was meant to be at all which was weird based on it's popularity and name etc but anyway..

Questions is any reason my preview function should not work but the entire avi is fine?
