DVD storage capacity (around 9 gigs on a double-layer disk if memory serves).
BluRay storage capacity (50 gigs on a double-layer disk).
Both players/recorders use laser diodes to read/write, but each uses a different wavelength of coherent light. The higher frequency Blu Ray affords much greater storage efficiency.
As for any differences in audio/video fidelity, Blu Ray is naturally better, but not to these eyes/ears.
Yes.
Blu-ray discs have a better image resolution, high definition and better graphic detail then what the normal Dvd disc would have.
The actual blu-ray player is a lot different then a regular dvd player. The laser inside the Blu-ray players are a smaller size, making them not compatible for standard dvds. However, Blue-Ray players CAN play regular dvds, but the graphics won't be as top notch as they would be with an actual Blu-ray disc.
