Sorry about the compression problems I did try to encode the MKV straight from my ProRes HQ master but unfortunately this was a no go and not wanting to spend too much time on it I decided to use handbrake to encode the MKV from the DL-DVD I had authored for previewing purposes. As for next time, there wont be a next time :p I only plan to release this in DVD format, the MKV was just a way of putting a work print out at 1/4 the size of a DL-DVD.

As far as the DL-DVD I authored up for previewing goes, I used the highest possible bit-rate my MPEG2 encoder supports 7.7mbps VBR with a max of 9mbps.

Sorry I meant final version. I know you said the mkv was just to test things, but wasn't sure if you were releasing the finished thing in .mkv again or DVD. Since you are going with DVD and the MPEG2 encoder will be better than handbrake, it sounds good to me! I was impressed with the colouring Lee, but it was hard to judge it properly with the compression, so I hope you don't take offense.
