Question: It has been almost two years since the first volumes of "WKRP in Cincinnati" and also "The Practice" were released on DVD. There has been nothing since. Are there plans for the release of more volumes for either and/or both of these TV series?

Answer: Not that I know of.

The "WKRP" set was a disappointment for many fans because it did not include the original music from the show. Quite a few shows will release a first season, or even the first few, and then stop because sales do not live up to expectations.

On the other hand, some shows — especially science fiction and fantasy, with a devoted and free-spending audience — will not only be released in their entirety but repackaged and re-released.

But there's always hope. Fans of "Everwood" finally saw the second-season hit DVD recently, close to five years after the first season's release.

And new media are providing some opportunities. Episodes from the first three seasons of "The Practice" are on Hulu.com.
