Actually the 3rd and 4th DVDs I didn't do until this morning after 1st 
booting and the box was off for several hours. When I remove the media 
it does not feel hot, and I am able to do several back2back copies of 
DVDs with k3b without any problems. In fact that's how I copied the 3rd 
and 4th DVDs and then 3 double sided disks of the 1st season of House. 
Each disk/side was done one right after the other with no stopping. Now 
playback is a different story as there seems to some dropping and 
freezing happening. I'm not sure if it's the harddrive or the CPU. The 
harddrive is a 500GB SATAII on an Adaptec dual port SATAI HA and the CPU 
is an AMD Athlon 1800+ with 1GB RAM.
Any ideas or maybe I should encode the images? (or is it transcode?)
