[MPlayer-users] Smooth DVD Playback And OpenGL

[Jason Van Cleve]

Rob, thanks, but your suggestion comes right out of the doc's, which
I've read more than once already.  As I said, DMA is enabled on my
drive:  if it weren't, Xine and Ogle would probably play funny too. 
Here's my output from hdparm (probably just like yours):

/dev/hdd:
 HDIO_GET_MULTCOUNT failed: Invalid argument
 I/O support  =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 HDIO_GET_NOWERR failed: Invalid argument
 readonly     =  1 (on)
 readahead    =  8 (on)
 HDIO_GETGEO failed: Invalid argument
 busstate     =  1 (on)
 HDIO_GET_ACOUSTIC failed: Invalid argument

Sergei, as I've mentioned, I've tried the -cache option already, using
several different values from 256 up to 20000.  The result is always the
same, which suggests to me this is a problem in the video output chain,
not the IDE read process.

Any other ideas?  Sounds like I should make a bug report, but I'm
hesitant about that, because there are really two separate issues here,
DVD video output and the GL modules.
