Hi, i am trying to enable dma in Redhat 8 on my dvd drive, so i can watch dvds. mplayer plays them, except that they are jerky when the dvd has to keep reading, then pauses between reads. I tried adjusting cache options for mplayer with no luck, and tried adjusting the speed of the drive. does anyone know why |# hdparm -d1 /dev/cdrom | |/dev/cdrom: | setting using_dma to 1 (on) | HDIO_SET_DMA failed: Operation not permitted | using_dma = 0 (off) fails. the dvd drive is a fairly nice (panasonic?) dvd drive, that plays dvds admirably in windows (when media player will let it...) thanks.
