second patch set with gui support.

apply within my dir structure or correct diff headers, pls.

drive media hw error correction is toggled by checkbox "ignore read 
errors" now (for dvd read10 cmd only at this time).

dont know if the reader is reset after using, apply hdparm -w /dev/(dvd) 
   to be sure before copying data discs again.

y
