Question

Hi, I have a question. I recently got a new video card and started playing emulator games.

1. I have a single horizontal blurred line that moves down and up the screen slowly, how do I get rid of it? (does not show up in screenshots, only when moving up/down)

2. Is there a way to smoothen the screen completely so that there aren't small skips (may be related to above question for me, I am not sure)

system info:
athlon xp 2200+
576 mb SDRAM
128 mb 256-bit ATI Radeon 9800 Pro
win 2000 prof

I run the games through an emulated cdrom (daemon tools)
