Fat lot of good that did. The *live action elements* were shot that way, but the whole situation with the effects...you can't really describe without using the word 'cluster'.
I believe those machines actually use a fancy resize algorithm to scale the SD to HD resolution. You don't gain much from it, but it can be better than letting the TV scale the image (depending on what the TV itself would do). Some resize algorithms are much better than others.
Most HDTVs, such as the Pioneer Elites, will have much better upconverters than any DVD player ever could have. I bought the particular Blu-Ray player I did (a Sony) specifically because I could *disable* its upconverter for standard def DVDs - I want my TV to handle all that.
