I hope you are not referring to a comparison of a DV139 vs a Blu-ray player here. In the worlds of comparisons and opinions of all things audio and video related, Blu-ray (PS3) is a QUANTUM LEAP above DVD (DV139) on a 50" Pioneer PDP-507XD. The difference in resolution is obvious and I am talking here as Alba boom box vs Arcam Hi-fi obvious. The colours and richness of the image on Blu-ray is way, way beyond that of DVD and that is a fact. This is a silly argument and makes the DV139 out to be a miracle, which it is in an audio sense but for video, it really is one of the best DVD players available but is in ABSOLUTELY no way comparable to Blu-ray.
