I installed a LITE-ON 16X DVD ROM drive (Secondary Slave) in my father-in-law's PC, the config of which is ASUS mobo P3W, P-III 500MHz, Hynix 256MB SD RAM, 80GB Seagate Barracuda HDD, LG 17" CRT monitor, ASUS CD-Writer (Secondary Master), OS Win 98 & WinXP (Multibooting). DVD & DivX videos are displayed in jerky motion in WinXP, though VCD video plays okay. Is the onboard 4MB Video RAM too low for DVD playback ? Will DVD video play okay in Win98 or will I have to go for a P-III 700Mhz or up CPU ?
