I have a PS3, hooked up to to a Samsung 1080p DLP, via HDMI (actually though a switchable HDMI Denon Surround Sound receiver). The unit plays Blu-ray disks wonderfully, and also plays Tiger Woods golf, and NHL Hockey, which I guess are both 720p games. For some reason, when I load NBA07, it runs through the title and legal disclaimers, shows the logos and says it's loading..then the machine hangs, the screen goes blank, and I have to reboot. I've exchanged the game thrice, and actually had the Best Buys store play the game on their demo setup..It worked! But, I noticed they were using a 720p LCD display, not 1080p like my setup. When I called Sony Technical support, they had me reset the system, and that didn't work. By the way, I did download the system upgrade (was required to, in order to go online). Their answer now is to send them the system for replacement or repair, but I don't want to do that. I also don't think a different PS3 will fix the problem, as this sounds like some sort of 1080p scaling problem. Anyone out there have a solution?
