I have an FC3 system ASUS P5GD2 deluxe with a Plextor PX-716A DVD burner. When I try to play DVDs in this drive the frame rate is horrible. Jerky playback, dropped frames. I ran xine-check and I found that DMA does not appear to be set for this DVD drive. I tried setting DMA on using hdparm -d1 /dev/hda But I get the following: HDIO_SET_DMA failed: Operation not permitted I checked the jumper settings on the drive and the bios settings and best I can tell they should allow DMA to be setup. The other odd thing I have noted is that when I insert a DVD or CD in this drive I have to manually mount it to access it. I used this drive to load the system from the FC3 CDs. I have used this drive to burn a CD-RW with no problems. Ultimately trying to get this drive to work with Mythtv. Any ideas on this one? -- Scot L.
