I knew this was coming soon!
Especially since you took a break from DK... the formula seems to be push, push, push, then walk away for a while. When you come back, you're fresh, but all the training has seeped into and marinated in your brain and you crush. I've seen (and experienced) this pattern over and over again.
As for getting it onto DVD, that's going to be tricky, and it could be a TG problem actually, because Twitch splits videos into half hour segments. It will not be unbroken.
One piece of advice I would give to everyone, regardless of what software you're using, is *always stream to a local file along with the live stream*, absolutely and especially if it's something that you'll potentially submit to TG.
You'll avoid the filesplitting, and also end up with a better quality video because the streamed version will have dropped frames, etc., depending on the quality of your Internet connection.
Never trust Twitch with your stuff. (In fact, never trust the Internet in general with your stuff.)
In any case, enter the URL into this tool and you can download the segments here:
