HBO, CineMax, The Movie Channel, Showtime, and Starz/Encore (missed any?).

You missed Starz. And this should've been a poll

I'll watch all of them from time to time.

Do you mean currently running, or ever?

Entourage, Curb Your Enthusiasm.

Buy Weeds seasons as they're released...

You realize that most of the channels you're talking about (aside from HBO and Showtime) don't host original programming, right?

Isn't Crash the series supposed to premiere on Starz this fall? I would love to watch that, but I don't really like Starz and shelling out $13 bucks a month for it as out of the question.

I didn't mean which one you watch the most, but which shows you watch on a premium channel (Hence no poll)

I don't get any premium channels. I canceled HBO when they canceled John From Cincinnati.

I cancelled HBO after In Treatment, John Adams and Bill Maher ended. I will re-subscribe when Maher comes back in August, or maybe in July for that Generation Kill mini-series.

I have Showtime (currently free) to watch Weeds and Secret Diary of a Call Girl. Will also watch Dexter, L-Word, and Californication when they return.

I definitely watch more shows on Showtime now than HBO.

Currently I'm watching Penn and Teller and some show about hookers that my wife thinks I'm watching with her because I'm in tune with "women's issues" (or some shit) but I'm really watching because I want to see Billie Piper nekkid.

Nothing since Red Shoe Diaries and Beverly Hills Bordello were cancelled.

I don't have any premium channels.

But I've watched these on DVD: (all shows completed or current in my collection, unless otherwise noted)

HBO
Band of Brothers
Carnivale
The Comeback
Flight of the Conchords
The Larry Sanders Show (I've got season one, but not the "best of" stuff)
Mr. Show
Sex and the City
Six Feet Under
Sopranos (only seasons 1-3)
The Wire

Showtime
Californication
Dead Like Me
The L-Word
Masters of Horror
Penn & Teller: Bullshit! (only seasons 1 and 2)
Weeds

And I'd love to see It's Garry Shandling's Show released on DVD sometime, too.

Showtime:
Weeds
Dexter
Californication

HBO:
Big Love
Tell Me You Love Me

HBO: Curb Your Enthusiasm

Showtime: Weeds

Everything else has sadly ended and/or I own on DVD.

I'm very close to getting rid of all my preminum channels, actually.

Entourage and Curb Your Enthusiasm. I wanted to get in to Deadwood when it was on, but never got the chance.

I don't subscribe to Showtime but I've seen and enjoyed both Weeds and Dexter.

Nothing now. Waiting for Big Love to start up again.

In Treatment got greenlighted for Season 2.

I don't get any premium channels

Neither do I. I go the DVD route and whatever is on regular television.
