I installed a new Delta 12x DVD-ROM on my computer, and everything was and is working good untill I tried to play an actuall DVD disk in it, I got a message saying the DMA setting was not on so I went to the setting to turn it on and did the restart. I tried the program again and got the same message. I checked the settings and DMA was once again unchecked. What I want to know is this a driver problem, or a system problem. The computer is a 400mhz celeron, intergrated vedio, with a V21000 video accelerator installed. Let me know if you need more info and I will post it. Thanks in advance.
