Harvey, You didn't say which version of windows you were running, but if it's xp, then you are out of luck....for now. I have the same video card and have discovered that ATI isn't supporting it yet. You might want to check out their web sight at.. http://support.ati.com/products/pc/radeon/winxp/radeon_winxp_drivers.htm l?cboOS=Windows+XP&cboProducts=ALL+IN+WONDER+RADEON&cmdNext=GO%21 As an alternate piece of software you can use Power DVD. Hope this helps. Brian in Indy I'm upgrading my computer to DVD. I have a Pioneer DVD 106S replacing my CDROM. My sound card is a Diamond MX300. I have a All in Wonder ATI Radeon installed. I've set the DVD to DMA , My computer is a 450Mhz Intel ABIT BX6 board. I have installed the latest drivers for the video display. The Drive plays audio CDs and reads other CDROM okay. The message I get is: Audio device is in use or not installed, display overlay is not available or not enough memory. I have 256Meg of ram. Can anyone help me.
