Im getting an error with mplayer a few seconds after starting. Too many vidio packets in buffer.
In Xine im getting The source cant be read, maybe you dont have enough rights for this etc. with-xine: cannot find input plugin for MRL [dvd:/]
xine: input plugin cannot open MRL [dvd:/]
xine: found input plugin : DVD Navigator

xine-check=[ hint ] You don't have a /dev/cdrom device.
This is the default device that xine uses for playing VCDs or CDs.
You could make your life easier by creating a symlink named /dev/cdrom
pointing to your real CD device (something like /dev/scd0 or /dev/hdc).
If your cdrom device is /dev/hdb (slave ATAPI device on primary bus),
ln -s hdb /dev/cdrom
typed as root will give you the symlink.
Alternatively, you can configure xine to use the real device directly,
using the setup dialog within xine.

[ good ] /dev/dvd is /dev/dvd, not a DVD device
The /dev/dvd is a dvd player and burner.

Help please
Thanks
