Yes, but the Video Availability page that I linked earlier has links to the LRR page, YouTube, Blip, the Escapist, and PATV for the videos listed. (In the cases when such a link is available, that is.) I found "Rejected 'Get a Mac' Ads" on YT, here: http://www.youtube.com/watch?v=bCA9xi2Um84 but it hasn't been embedded to the main site yet. Unless what you're talking about is that fact that many reuploads haven't been added to the main site yet, in which case, I apologize for misunderstanding.
That said, I agree about it being a shame. I recently tried to watch through "The Whatever Thing" and "Phailhaüs", but chunks of episodes were missing from both. It sucks, but they're busy and I get why it's one of those things that gets pushed back.
ETA: Stupid coding. Sorry, about that.
