Got a new Samsung Super-writemaster SH-S182/RSMN.
It burns fine -when playing the burned DVD on the PC the play is "stop and go".
i.e. the movie plays for 2 seconds then stops for some time and then runs again for 2 seconds. and so on.
When usning FFW it rund continuously.
DVD disk works fine in any other DVD player.

What's the problem - I got a new Super writemaster from my shop already and problem is the same.

Thanks for your help

From togaware;

If watching a DVD seems a bit choppy (stops and starts) then perhaps the CD/DVD IDE device needs some tuning. First check to see what the current settings are (e.g., on Belinos (103.5) where the DVD driver is /dev/hda):

$ hdparm /dev/hda

/dev/hda:
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
HDIO_GETGEO failed: Invalid argument

For a DVD, setting the readahead to 8 (-a8) seems to fix it. Turning unmask on (-u1) also might help:

$ sudo hdparm -d1 -a8 -u1 /dev/hda
/dev/hda:
setting fs readahead to 8
setting unmaskirq to 1 (on)
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
unmaskirq = 1 (on)
using_dma = 0 (off)
readahead = 8 (on)
