I tried this:# /sbin/hdparm -d 1 /dev/hdc /dev/hdc: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) I tried the same for /dev/dvd (which is a sumlink to /dev/hdc) with the same result. Also mplayer doesnt play any DVD's but Xine & Kaffeine do (although with the slow,choppy issue)
