Thanks to EyeShotFirst Oldschooljedi, canadianbs101 and ThiefCobbler4ever for the kind words :-) I'm glad you like it.
As to the sound mix, like hairy_hen already said, it should fit his 5.1 mix without the need to set any delay, only then it won't fit a DVD5 AND I definitely wouldn't recommend recompressing the video of the NTSC DVD5. Chainsawash should be fine with recompressing the MKV.
