First of all when I start up the TV tuner program to input a signal from my PS2 I immediatly get this message:

I know for a fact DMA is enabled on my hard drive, it is set to UDMA2. So what the hell? What's wrong here?
The next problem is the picture quality. I use the basic PS2 input cables (composite) to get the signal to my video card and the picture quality is SHIT, extreme emphasis on shit. Is it because I'm using composite and would it improve if I use S-Video? Here is a picture from Soul Calibur 3 to show how low quality the out picture is (thumbnail):

And finally the biggest problem of all... the games are unplayable considering there is a 1 second delay from when I input a command from my PS2 controller. I know for a fact people have this working without any lag using crappy old beaten up ATI TV tuners so what's wrong with mine?
I would seriously like to play my console games on my monitor rather than the current TV in my room so if anyone uses an ATI All-In-Wonder card and may know what's wrong here any advice would be helpful. Thanks in advance.
