It's been a few years ago, so I forgot the source. Pretty sure it's not a reliable one either.
If that's the case though, I wonder why the HD versions aren't even available, considering it's as somewhat popular as Happy Days or Star Trek.
What's preventing Seasons 7-11 of Happy Days being released on DVD, as well as Seasons 6-12 of My Three Sons?
For Happy Days, it's probably music rights, but I don't know if that's the real reason.
A Blu-Ray (HD) release of The Brady Bunch would also be great, but as far as I know/heard, an HD...
