When I open a video encdoded with DivX and watch it it looks great, no artifacts. But when I maximize it I get articfacts. Okay, I guese that makes scence. But when I take a very close look at the origonal non-resized video there are none. So I tried this: I droped my res to 800x600, making the video bigger without resizing it. there were no artifacts.but when I resized it even bigger to full screen (it was 320x240) I can see them, but I can clearly see that they do not exist prior to resizing. This is all done using BSPlayer. Why is this, Why can't I resize the video and not have any artifacts. I mean the Big blocky ones, not the other ones that I am expecting to see. Is there a way to lower my res to 320x240 in WinXP so I can loose the artifacts?

Thankyou

I´m not entirely sure, but you are only PLAYING the movie, correct? If so, I guess it´s because the player has to resize the picture(s) in real-time, thus having not enough time for detailed calculations.

The only thing I could recommend would be to edit the file using VirtualDub and using the resize-filter. It´s much better than (for example) the MediaPlayer algorithm, and you can "clean" the video too.
