k9copy crashes and mencoder goes wacky in Natty

[coacharnold]

Hello,
Recently upgraded to Natty, and too my dismay K9copy crashes when I try to convert a DVD ISO to an .avi ..... so I started playing with mencoder and as well the script below. The script works but every time I use it my video goes crazy, lots of random pixels all over the place. Restarting X does nothing, I have to actually restart the computer. Once I do ..... everything is OK .... the .avi file even gets created perfect.

This also happens when I just use mencoder from a prompt like this -------- $ mencoder foo.ISO -ovc lavc -lavcopts vcodec=mpeg4:vhq:vbitrate="1200" -vf scale -zoom -xy 640 -oac mp3lame -lameopts br=128 -o bar.avi

At first i thought it was my video card dying (nvidia 8500) but I can recreate the issue by simply just using mencoder.. I'd rather use K9copy ...

anyone have any ideas?

script I used that works (but foobars the system) is below
