This week, I answer questions about TV shows on DVD.

One of the greatest guest stars in Scrubs, nay, in television history will make his triumphant return soon.

Tom Cavangagh told TV Guide he will make another guest appearance on Scrubs as J.D.'s older brother Dan before the final season's hourglass runs out of mortality sand.

Cavanagh confirmed the news by saying the "chances are 100 percent" that he'll get to go back on the show this season. Cavanagh will also star in the TNT show Trust Me with Will & Grace star Eric McCormick and Scrubs regular Sarah Chalke.

(S01E10) The title of this episode was called "Heartbeat" because Eli's case involved a heart transplant -- two actually -- but "Reflections" might have been more appropo. Eli awakened in Nate's body and continued to find himself reliving his brother's life ten years before. And not on just any day, but the day that their dad died.

Overall, this was a particularly interesting episode because it seemed to lay the groundwork for where Eli Stone is going. Since it's likely that the show is going to be renewed -- deservedly so -- the prospect of Eli getting that surgery which may correct the aneurysm that's causing his visions, may not be happening after all.

We've speculated about this many times here at TV Squad, but now we have word from Ed himself, Tom Cavanagh, that season one of the show is coming to DVD.

In an interview with Collider.com, Cavanagh says:

"Yeah, I guess they're talking about it. Last I heard was they were close on season one. The stumbling block as it's like a lot of the time is the music rights. They were fortunate enough because of the clout they had as Letterman's producers to get a lot of great music as one-offs. Of course, when you put those on a DVD that becomes a whole different thing."

Tom Cavanagh, known for his goofy-but-sweet roles in Ed, Love Monkey and Scrubs, is going all nerdy on us! He's going to host six episodes of a backstage pass-type show for the Smithsonian Institution.

Last year, the Smithsonian announced it is creating a television channel with Showtime that will launch in April. There are at least 60 programs planned, with a few already in the works. One of those few is Cavanagh's Stories from the Vaults. The premise of the 30-minute series is that Cavanagh gets to take viewers behind-the-scenes to check out some of the Smithsonian Institution's coolest and oddest artifacts.

The Smithsonian programming is being offered to cable and satellite profiders as an on-demand channel. Many of the other programs will focus on Smithsonian research, which is not as well-known as its artifacts. So far, no television providers have picked it up.

I was bummed when the show was canceled so quickly by CBS, and really happy when the show was picked up VH-1 (well, the episodes already in the can), so why did I forget to watch it last night? I have to remember, it's on VH-1, Tuesdays at 9. VH-1, Tuesdays at 9. VH-1, Tuesdays at 9!

Luckily, the networks repeat everything a lot now, and this episode (titled "The Window") will be repeated this Thursday at 11am. I'm going to set my DVR just in case. The Price Is Right is on at the same time.

Don't you hate it when you're looking forward to seeing something, but you get busy and it slips your mind and you miss it?

Thank you, VH1!

The music network will air all eight episodes of CBS' cancelled Love Monkey beginning next month. That's five episodes we haven't seen, since CBS prematurely pulled it from the schedule (damn you, CBS!).

The first three episodes of Love Monkey (the ones we've already seen) will air back-to-back starting at 7 pm (ET) on April 11. The remaining episodes air weekly on Tuesdays at 9 pm (ET).

When the new fall shows were announced, I was kinda bummed that Love Monkey didn't make it to CBS' schedule. I was a big fan of the late NBC show Ed, and was hoping to see star Tom Cavanagh in another show. Now it looks like it will happen after all. The network has ordered the show as a midseason replacement, in case one or more of the other shows doesn't catch on (maybe Ghost Whisperer? Hmm? Maybe?).

Love Monkey is based on the book by Kyle Smith and is about a single thirtysomething record exec (Cavanagh) who has to deal with all his married/deeply in love friends. I can relate. Except for the thirtysomething part.
