I went back to Windows XP and saw that it was setting the DVD drive mode to "Ultra DMA Mode 2", wich is 33.3MB/s. So I went back to Suse and using Yast forced the DMA mode to UDMA/33 (remember Suse is setting the DVD drive speed to UDMA/66) and the DVD drive worked perfectly. I watched an entire encrypted DVD (ID4) flawlessly just to be sure. This indicates a few things. First of all, it appears that Suse is detecting the DMA mode incorrectly, or at least not adjusting to what it really is. There must be a way to do it accurately, because the drive is set to the correct DMA mode by Windows XP. Secondly, and this is the worst part, if a DVD drive doesn't work at the expected speed it appears that Suse doesn't try any other DMA modes, it just drops the drive into PIO mode. There may be valid system stability issues requiring this, but I have a feeling it's what's causing the plethora of "jittery DVD" and "mysterious DVD/DMA" complaints I'm seeing on Google. I hope this helps. I'm reassigning the bug in hopes in can be fixed, and that it will enable a lot more customers to adopt openSuse. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
