A week? As long as that?!
Just kidding...take your time.
If you are going to encode the rest of the seasons, it would be great if you did 1,2 and 7 as well.
Downloaded a few eps of mr-vanadalay's links. I'm grateful, don't get me wrong, but for the given file size, which is similar to yours, the quality is not as good.
IMHO, yours gets 9/10 for video and 9/10 (occasionally out of sync) for the encoding. His get 7/10 for video and 6/10 for audio.
So please, if you have the time, energy and patience, would you do 3-6 first and then 1,2 and 7?
