Heya :)
I have just started recording some vids of individual levels, so far I have done 7-1x (http://www.youtube.com/watch?v=AH1ZYeN0Elo) and 7-13x (http://www.youtube.com/watch?v=feKm4aBLGuk)

Sorry about the quality, I am using xsplit local recording mode and I dunno how to improve it without making SMB lag while recording. I think it's still watchable though. Lots more to come :)
