before hdparm -X66 -d1 -u1 -m16 -c3 /dev/hda was:

/dev/hda:
 Timing buffer-cache reads:   1120 MB in  2.00 seconds = 560.00 MB/sec
 Timing buffered disk reads:   12 MB in  3.45 seconds =   3.48 MB/sec

after hdparm -X66 -d1 -u1 -m16 -c3 /dev/hda is:

 Timing buffer-cache reads:   1108 MB in  2.00 seconds = 554.00 MB/sec
 Timing buffered disk reads:   86 MB in  3.01 seconds =  28.57 MB/sec

Neither HD nor DVD player were enabled with DMA, I got it by hdparm:

hdparm -X66 -d1 -u1 -m16 -c3 /dev/hda set the DMA on as well:

/dev/hda:
 multcount    = 16 (on)
 IO_support   =  3 (32-bit w/sync)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    =  8 (on)
 geometry     = 9729/255/63, sectors = 156301488, start = 0

and that's my dvd player: 

/dev/hdb:
 HDIO_GET_MULTCOUNT failed: Invalid argument
 IO_support   =  0 (default 16-bit)
 unmaskirq    =  0 (off)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  1 (on)
 readahead    =  8 (on)
 HDIO_GETGEO failed: Invalid argument

and after all HD stored AVIs are smooth with Xine..so maybe it's a Mplayer setting. I dont' know!

Bye and thanks
