Slow On-screen Graphics

[Noel]

I have an IBM, Intel Pentium III 550mhz with 128meg of Ram, and 16 Meg on the video card. An IDE Sony CRX145EBK writer set as the master drive. It copies whole discs perfectly, makes compilation CDGs (up to 21 tracks on a disc) perfectly, and makes perfect CDGs from the KHP program. The only problem I have is the play feature - from hard drive, or disc the graphics on the computer screen scroll perfectly, but very slowly, and way behind the music. Since my video card has twice the required memory, It couldn't be that, or could it still be the video card? Is there a setting I can change?
