I received both on Saturday, so they're definitely out there. (Didn't do RUNNING COOL. Never seen it. Should I?)
Like Jimmy said, I imagine they just underestimated the demand and didn't ship Amazon enough off the bat. I wouldn't think it's anything to get alarmed about.
I haven't sat down and watched them proper, but the screencaps above pretty much show what the prints are like. They're nicer than the old VHS tapes, but are still analog-based masters -- possibly created by Paramount for cable airings or something. There are also some minor compression issues to be had. So, an upgrade of anything I've seen for the titles, but not as good as fresh scans from original elements would've given us. Each disc also has a Q&A with Beverly and Ferd, along with some ridiculous promos for their "causes."
