I assume your Fry's was playing the DVD version which would in fact show a lot more artifacts then a potential HD-DVD/blueray copy. Or it could have just been the mediocre special effects in that movie. . . rated two thumbs down, by me!

<br>Whoops. I did in fact mean lossy compression not lossless. I take full responsibility for any confusion resulting from my typo.<br></div><br>-- <br>_____________<br>Ryan Patterson
