no, as you are limited by 1280 x 1024 resolution.
you will notice no difference
Completely untrue. HD dvd will look crisper, no blocky images, more detail and best of all less artifacts that mpeg2 causes with dvd.
I think what mm is saying is that 19 inch is small in that it doesnt take full advantage of the resolution hd dvd offers, however you must keep in mind that if you are watching your movies sitting right in front of your monitor the HD dvd will look much better. IF your sitting back away from your monitor then you might as well just stick will DVD.
The fact that your using a 19inch 4:3 makes things alot worse in your situation, as your monitor will be displaying half it\'s resolution when playing widescreen movies.
