Making Video - DVD to Computer Monitor

Hi there,

I'm trying to find out how to do this without loosing quality. I've got to make a product show for my friend when he goes to his presentation. The video will run from a DVD to a Monitor via a HDMI to DVI cable.

Yet it seems this method causes to much quality to be lost. I'm not sure what video setup I should use.

For instance PAL DV 720x576 (16:9) which has the 1.4 pixel aspect ratio OR

use the square pixels PAL DV which is 1050x576.

Can anyone clarify which would be the best or an alternative, I was thinking maybe just creating it in 1080P then running it from a computer?

Thanks.
