Yeah the PS1 bios will show ok. And sometimes the games will too. But sometimes the cut scenes won't show or will be off. Sometimes it's the title screens, sometimes it's the whole game, depends on the game. It's rather annoying because I like component on the PS2, and hate not being able to play PS1 games on it. This is on a 42" Polaroid 1080p LCD TV. I guess I could try hooking it up via component onto my 50" Toshiba standard definition TV and see what happens.

Does anyone else ever have this problem playing PS1 games on their PS2 using component cables on an HDTV?
