Question: what is the difference between a blu ray player and a dvd player?
Answer: The biggest difference is in the capacity of the discs. Blu-ray boasts up to 25 GB on single-layer discs and 50 GB on double-layer discs, with HD DVD at 15 GB and 30 GB. ... Both HD DVD and Blu-ray players are backward compatible with older DVDs, and both can upconvert regular DVDs for viewing on an HDTV.
