These vids were done with Avid Free DV, which forced the bitrate down to 700kbps if I recall. I wasn't satisfied with their quality when I made them as the finer details were fudged slightly. I've been wrong before but I only saw the differences as simple display methods between the Dreamcast and PS2 with Code Veronica.
If you are watching these videos on youtube make sure 480p is selected. The original video quality is better than that though.
Trekkies, I don't own the Gamecube version of Code Veronica X and haven't compared it before.
Since this topic is busted anyway, I find the comparison of Resident Evil 4 between the Gamecube and PS2 much more interesting.
