Read the serial HOWTO, the remote-serial-console-HOWTO, the text-terminal-HOWTO, etc. Then you run minicom or other terminal emulator. File transfer via the rzsz package that integrates into minicom.

install memtest86, run update-grub, reboot and choose the memetest86 option and wait, see if you have any memory issues. I've had this happen a few time, so could be bad memory in there some place.

You passed the '-Y' argument to ssh, which enables trusted X11 forwarding. That gives applications on the remote host full access to your local display.

This may be because of new forms of copy protection they are adding to DVDs. A DVD player navigates through the disc based on the structures in the VOB files, so it can be told to skip blocks on the disc. If you try to read the disc as a UDF filesystem, you'll hit the blocks that the VOB navigation skips.

The copy protection works by making those blocks bad so you cannot do a block by block copy of the disc.

If you get a recent version of vobcopy (http://vobcopy.org/), it should be able to make a copy of the disc which can then be played off the HDD.
