That’s the pitch Apple has been making to TV networks in recent weeks. The company is trying to round up support for a monthly subscription service that would deliver TV programs via its multimedia software, multiple sources tell me.

Apple (AAPL) isn’t tying the proposed service to a specific piece of hardware, like its underwhelming Apple TV box or its long-rumored tablet/slate device. Instead, the company is presenting the offer as an extension of its iTunes software and store, which already has 100 million customers.

A so-called “over the top” service could theoretically rival the ones most consumers already  buy from cable TV operators–if Apple is able to get enough buy-in from broadcast and cable TV programmers.

That’s a big if: Apple has told industry executives it wants to launch the service early next year, but I have yet to hear of a single programmer that has made a firm commitment to the company, which has tasked iTunes boss Eddy Cue with promoting the idea.

Industry executives believe that if anyone jumps first, it will be Disney (DIS), since CEO Bob Iger has shown a willingness to experiment with Apple and iTunes in the past: In 2005, Disney was the first player to sell its programming on iTunes, via a-la-carte downloads. And Apple CEO Steve Jobs is Disney’s largest single shareholder, a result of Disney’s 2006 acquisition of Jobs’s Pixar animation studio. Apple didn’t respond to requests for comment.

Network executives I’ve talked to are intrigued by the idea–they are eager to find new revenue streams–but are also wary, for several reasons.

Cable networks, for instance, don’t want to threaten existing relationships and subscription fees from cable providers like Comcast (CMCSA). And programmers are also worried about the effect a subscription service would have on advertising revenue: Even if the service didn’t distribute TV programs until after their initial air date, that could cut into ratings, which now measure viewership over the course of several days.

But the move to deliver TV and movies over the Web is already well under way. Netflix (NFLX), for instance, already bundles free streaming movie and television along with its disc-by-mail subscription service. iTunes and Amazon (AMZN) rent movies on a one-off basis, and Google’s (GOOG) YouTube is trying out the same thing. Meanwhile, Hulu, the joint venture between GE’s (GE) NBC, News Corp.’s (NWS) Fox, and ABC, is figuring out how to launch a paid service that may include rentals, paid downloads or subscriptions.

So Apple’s proposed subscription service, which the company has floated in the past, is no longer a huge stretch. Says one executive briefed on the company’s plans: “I think they might get it right this time.”

Could Comcast (CMCSA) be talking to NBC Universal about…something? Could be–that’s what the Los Angeles Times and other outlets reported last night.

And Comcast’s statement says there’s no “deal,” which doesn’t preclude “talks about deals.” Then again, it’s awfully unusual for a company in Comcast’s position to say anything at all.

Clear as mud? Then this won’t help. Check out these comments from Comcast COO Steve Burke at a Sept. 9 conference hosted by Bank of America (BAC) where analyst Jessica Reif-Cohen asked him about his appetite for acquisitions.

Burke said he’d love get more cable channels (like the kind NBCU owns). And he said he didn’t want a really big deal that would require the company to use its shares or take on a lot of debt (like, say, a $35 billion deal for NBCU). He said all this, by the way, in the span of a single answer.

I’ll carve it up and translate for you:

We’ve had plenty of debt, and we don’t want any more right now, thank you very much.

Well, if you look at cable companies over the last 10 or 20 years–I joined the Company 11 years ago. It is really amazing how deleveraged our Company and other cable companies have gotten….We like where we are from a leverage point of view and I think [we] would be uncomfortable if our leverage was significantly higher.

But boy oh boy, are cable channels attractive!

At our core, we believe that content and distribution work well together….I think there are a lot of case studies where content and distribution, particularly in a world where the distribution has technology that can deliver content in new and innovative ways, you really can create a lot of value by putting content and distribution together, particularly if that content is cable content.

And again, when you look at the big media companies, the best businesses that all of us have in the entertainment business I think are the cable content channels and those channels with that dual revenue stream are really good businesses. And I think we wouldn’t be doing our job if we didn’t try to figure out a way to get bigger in those businesses. Those businesses are growing more rapidly than our cable business and if the opportunity came about where we could add cable content to our portfolio, I think we would do it.

But really, we’re not in the market for a mega-deal.

Just to sort of get it right out there, I don’t think that means doing a big deal with our stock. I think all of us think our stock is significantly undervalued. So I don’t think that means doing a big deal with our stock. I also don’t think that means doing a big $50 billion acquisition. I think it is more trying to find opportunities that are complementary with our core business, that don’t take our balance sheet and push it back into a position, which we have worked so hard to get it down.

Never say never!

We are going to try to make sure that we are disciplined and we have high IRRs and good free cash flow generation and we will see if anything comes available. If it does, we will certainly look at it.

Got it? Me either. The only way I can reconcile Burke’s comments with the notion that Comcast is interested in an NBCU deal would be if Comcast was talking about buying Vivendi’s 20 percent stake in the NBCU.

Comcast could swing that one without breaking the bank–the conventional wisdom is that it would cost something in the $5 billion range. And it would technically increase Comcast’s cable network holdings, as Burke says he wants to do. But not really: Comcast would be a minority shareholder with no clear path to control. And it wouldn’t get the “distribution plus content” benefit Burke was talking about last month.

Anyone else have any ideas? Feel free to sound off below.

Blockbuster (BBI) didn’t provide much detail. It boasted about fourth-quarter same-store sales and said 2008 earnings would be above expectations, and that’s about it. But it assured investors it was working “diligently” to figure out how to pay some $380 million in debt that comes due in August.

Alas, investors are giving the numbers mixed reviews. After Blockbuster put out its release, shares opened up at 61 cents–up almost 30 percent from Wednesday’s close. Now that the penny stock’s shareholders have thought it through, though, they’re selling again, and shares have dropped below 50 cents. At the beginning of the week, they were trading above $1 a share. A year ago, they were worth more than $3.

Related note: On Tuesday afternoon, as the Chapter 11 reports were surfacing, I happened to be talking to someone who worked with the company about a decade ago, when it still ruled the home video market with an iron fist. At the time, he said, Blockbuster used to get frequent calls from an entrepreneur who was desperate to get the video giant to work with, or even buy, his company. Good thing that never worked out for Netflix (NFLX) CEO Reed Hastings.

All of that, hopefully, would convince investors that the meandering media conglomerate had a plan, momentum, etc. And then they would finally lift Time Warner (TWX) shares out of the high teens, where they had been mired for many years.

But now an AOL-Yahoo (YHOO) deal seems stuck in neutral, the rest of the Time Warner empire is in cost-cutting mode, and a stock price in the high teens must look pretty good to investors, whose stock is currently worth about $9 a share.

Hence, a proposed 1-2 or 1-3 stock split, which Time Warner management wants shareholders to approve next month. From the SEC filing: “The Board of Directors believes that effecting a reverse stock split, resulting in fewer shares of the Time Warner Common Stock being outstanding, is likely to increase the market price and improve the marketability and liquidity of the Time Warner Common Stock.”

Translation: You got a better idea?
