Q: Is there a reason the first two seasons of "Knots Landing" were released on DVD, and not the remaining 12? Was the decision based on poor sales of the first two seasons?

A: "We'd love to release the rest of this series," the show's studio, Warner Bros., said in a widely reported statement in 2010. "The problem is that there are heavy music clearance costs involved. Our company is dedicated to resolving these long-standing music stalemates, but the process is very time-consuming. We certainly know of strong fan interest in this great series." The music rights appear to remain a problem. And they are made more so because, as TVshowsondvd.com has noted, sales of the first two seasons did not demonstrate widespread customer interest in buying other seasons. That lack of interest would not encourage Warner to invest in those music rights.

Still waiting for 'The Goldbergs'

Q: Do you know when "The Goldbergs" Season 3 will be released on DVD? I have researched everywhere on the internet and can't find anything. At one point, I did see somewhere that May 2017 was a release date, but it's still not available. It seems like the other two seasons came out pretty quickly, but Season 4 just ended and I'm still waiting on Season 3 on DVD!

A: The show has not announced plans for release on DVD of either Season 3 or Season 4, although representatives of the show did not rule out releases. For now, both seasons are available as digital downloads via iTunes and Amazon.

No more 'Wars' and 'Pawn'

Q: Will we see new episodes of "Shipping Wars" and "Hardcore Pawn"?

A: While I have not seen an official cancellation of either series, and there's always a chance of a show returning, I wouldn't expect any new telecasts here. Neither show has had a new episode since 2015.

Catching up on old stars

Q: I would like to know what happened to actors Robert Fuller and John Smith of the old western series "Laramie." Are they still living and how old are they? I think Fuller was on "Wagon Train" and "Emergency!" but the last time I saw him was on a "Walker, Texas Ranger," in the mid '90s. I never saw Smith after "Laramie."

A: Fuller is still with us at 83 years old, complete with a website, robertfuller.info. Although the Internet Movie Database does not list a screen credit for him since "Walker, Texas Ranger" in 2001, he still makes public appearances with his wife, actress Jennifer Savidge. During a June visit to the Memphis Film Festival, one fan, having learned Fuller no longer had his "Laramie" hat, presented him a specially made copy of the chapeau.

Smith continued acting after "Laramie," including in a guest role on "Emergency!" in the 1970s, but his screen acting ended around that time. He died in 1995 at age 63.
