Yes, DR JMK, check out which films are available in each format. This should be the final decision maker for you. Quality is the same. When I chose Blu-ray, Universal was the only major studio not releasing on Blu-ray. That was the basis for my choice.
Yes, HD-DVD player sales did well when Toshiba reduced them, but so did Playstation 3 sales when Sony came out with its new, lower priced model, so player sales aren't going to be the determining factor (yet). It's still a matter of which popular films can be had on which format that's going to determine a winner (if there is one).
