One widely cited objective test is Silicon Optix's HQV testing which puts the dvd playback through a series of image tests. Cheap players tend to do very poorly on these tests. There is also the Secrets of Home Theater testing which mainly consists of flag based challenges. On a calibrated display the difference between upconversion of different players become apparent with careful scrutiny. Many base it on what upscaling chip each player uses. Right now the top chip is the Realta, found in the new Denon 3800 BD player. Usually if you find out what chip a player uses you can figure out how good of a upconverter it is.
