Not the divx you are thinking of. This divx is a new generation codec that allows video to be more efficiently compressed.
sbMKE, 1080p is more than a slight upgrade. I haven’t bought bluray but I’ve watched the same movie on DVD then HD, night and day difference.
I’ve seen the full 1080p treatment on display sets - the Costco by my house keeps showing the Pixar Cars movie as a demo and it’s stunning.
But still, it seems a bit like a 3D movie - very cool but perhaps more than most folks will deem necessary for day-to-day life.
Big fan of the divx codec. I use it often. Great compression and great quality. Too bad the studios view it as a pirate format and hardware support isn’t more universal.
