To be fair there was a minor format war when DVD came out and now nobody minds.
Format war? Do you mean DIVX from Circuit City?

IMO there was no war, and obviously me and a few million others agreed and avoided DIVX like the plague.
The dvd format is the most successful consumer entertainment format
ever,
partly because there was NO format war. Though Sony early on, around 1995 IIRC, was going to go it alone (again!!!) with a version of their own, but through much negotiating they were convinced to stick with everyone else........and look what happened.
The selfishness of so many companies these days i.e. not wanting to cooperate with each other when designing a format for the mass market, is sooooo nauseating to witness. It is so frigging obvious that just like with a football or other sports team, if you work together big things can be accomplished! But no, they think - somehow - if they work by themselves they'll get much richer even if it means splintering the market. Uh huh, yea I sure see those Blu-Ray and HD-DVD players just flying off the shelves.
Lets be honest DVD is 13 years old. It's time for a new format. A little competition, while very annoying, is probably healthy.
Healthy for who, CEOs and their shareholders? What about us, the consumers? Many of us can barely afford braces for our kids, make payments on 5 year old cars and can't afford health insurance so we pray no one gets sick.
And wow, thirteen years: so very, very old............nah. The CD is 25 years old and still sounds great (please, no analog/digital debates

).
While I agree HD images sourced from a well-authored disc or clean signal during an OTA broadcast
can look stunning, many "old-fashioned" dvds can look
very good on that same monitor.
When those Sony SXRD sets arrived locally back in 2005, I took my
Attack Of The Clones disc up there and after we calibrated the 60" SXRD model, via a $150 dvd player/component connection that standard def picture looked just great....and that was standing six feet away from it! No scan lines, no video jaggies, beautiful color. And when I later bought the Superbit version of
The Fifth Element, and watched it on that TV and other large HDTVs of various technologies, if you weren't paying attention it looked nearly like HD (on all these monitors, in addition to calibrating them by eye or with certain discs'
THX Optimizer, I made sure to turn off any "image enhancement" modes, which almost always adds junky video artifacts to the image and also deactivated all video noise filters which soften the picture too much IMO).
