PS2 Upscaling on the 60 gig

[blitz6speed]

Ok, i now own every PS2 game ive ever wanted to own to play on my 60 gig PS3. It is a mighty fine collection. Ive been loving the upscaler on the PS3 till i finally got Disney Golf for PS2. The graphics looked HORRIBLE. I thought maybe its a weird instance. I got even more PS2 games and they all look AMAZING! Then today, i got the final ps2 game i was looking for in the mail, Street Fighter EX3, and it looks absolutely HORRIBLE. Its like there is a large, thick layer of mesh in front of the overlay of graphics. I then realized that both Disney Golf and Street Fighter EX3 are CD based PS2 games. So i looked and indeed, i had a 3rd! Popped in Marvel Vs Capcom 2, and its absolutely stunning! Gorgeous and without an issue. So, i am at a loss. Why do these 2 games (Disney Golf + Street Fighter EX3) look horrible on the PS3 upscaled?

I am using HDMI, 720p. I tried with it on Normal, Full Screen, Smoothing On and Off. Looked horrible regardless of the setting. Is anyone getting this on their system?
