i know mucore uplaods to youtube, and i think M! Countdown does too now, do the other 2 upload their shows anywhere yet?
http://www.youtube.com/user/Mnet/videos
Channel is gartbage though, only uploads at 480p
Better off going to the actual site
http://mwave.interest.me/program/program_view.m?searchProgramVO.program_id=74
or

Their 720p is still not clean but it's better than the youtube uploads
For SBS Inkigayo
http://www.youtube.com/user/SBSMusic1/videos
But it's even worse as it uploads currently at 360, it used to go to 720 but not sure why it varies.
The better options are at either
http://www.hulu.com/inkigayo
or
http://www.dramafever.com/drama/4114/Inkigayo/
Provided they aren't blocked where you live. But they are a week behind usually as they translate the dumb banter between the MCs.
And of course there is
http://www.youtube.com/user/MBCkpop/videos?view=0
which is the best as they do both MC and Show Champion and even go to 1080
Music Bank doesn't really have one as KBSWorld is still living in stone age.
