How would you be connecting it to your TV? Bluray players don't have scart outputs, only HDMI, component, composite, and maybe s-video usually. That aside, it might vary from film to film, but Bluray will have a better black level, so the picture will look much more solid and believable. In the darker areas, there will be more noticable detail. Because Bluray is less compressed, you will see finer details better, and you'll see far less edge enhancement. Whether a DVD disc will play on the Bluray player as well as it does on your current DVD player will depend on the player you go for. I find most budget models just not good enough for DVD playback - it's the higher end models that have better picture processing for standard definition. There's a huge difference here between a Panasonic BD60 and a Sony BDP5000ES. But then, there should be.
