Hi Michael, I notice that you are using 384 x 288 for the mpg1, I've done some testing on this and on older PC's 352 x 288 seems to give the best reproduction. I suspect this has something to do with this being an older standard res for mpg's on the PC thus old video drivers cope better with this format?. Certainly the same footage can look alot worse using none standard formats ( increased tearing, blurry etc ). I usually do one compression of the footage to mpg1 at 352 x 288 then stretch the sprite in director back to the original size of the footage ( maintaining the original aspect ratio).
