Comcast Digital Switch Impact on My Windows Media Center

Irritatingly out of line with what their commercials say, in my area Comcast, under the covers of the national broadcast digital switch, is sneaking in their own switch to digital, moving channels above 30 to their own digital format. Previously, I had Windows 7 Media Center running on a PC with a Hauppauge PVR500 which can decode two television signals at once setup to record shows I like. The XBox 360 works great as a Media Center client letting me easily watch the recorded shows over my home network on my normal TV.

Unfortunately with Comcast's change, now one needs a cable box or a Comcast digital to analog converter in order to view their signal, but Comcast is offering up to two free converters for those who'd like them. The second of my two free converters I hooked up to the Media Center PC and I got the IR Blaster that came with my Hauppauge out of the garage. I plugged in the USB IR Blaster to my PC, connected one of the IR transmitters to the 1st port on the IR Blaster, and sat the IR transmitter next to the converter's IR receiver. I went through the Media Center TV setup again and happily it was able to figure out how to correctly change the channel on the converter. So I can record now, however:

1. I can only record one thing at a time now
2. Changing the channel is slow taking many seconds (no flipping through channels for me)
3. The Hauppauge card can't know if the channel change worked. So if it tries to change to HBO (I get it for free with one of the Comcast packages) which is encrypted and the converted won't show, the channel doesn't change but the PC doesn't know it and ends up recording some other channel.

Outline View Internet Explorer Extension

I've made another extension for IE8, Outline View, which gives you a side bar in IE that displays an outline of the current page and lets you make intrapage bookmarks.

The outline is generated based on the heading tags in the document (e.g. h1, h2, etc), kind of like what W3C's Semantic data extractor tool displays for an outline. So if the page doesn't use heading tags the way the HTML spec intended or just sticks img tags in them, then the outline doesn't look so hot. On a page that does use headings as intended though it looks really good. For instance a section from the HTML 4 spec shows up quite nicely and I find its actually useful to be able to jump around to the different sections. Actually, I've been surprised going to various blogs how well the outline view is actually working -- I thought a lot more webdevs would be abusing their heading tags.

I've also added intrapage bookmarks. When you make a text selection and clear it, that selected text is added as a temporary intrapage bookmark which shows up in the correct place in the outline. You can navigate to the bookmark or right click to make it permanent. Right now I'm storing the permanent intrapage bookmarks in IE8's new per-domain DOM storage because I wanted to avoid writing code to synchronize a cross process store of bookmarks, it allowed me to play with the DOM storage a bit, and the bookmarks will get cleared appropriately when the user clears their history via the control panel.

Dr. Horrible Link Roundup

Doctor Horrible's Sing Along Blog is an Internet only show you may have already watched and heard everything about. If you missed this somehow, its a musical by Joss Whedon (Buffy the Vampire Slayer, Firefly) staring Neil Patrick Harris as an aspiring super villian who can't get up the courage to talk to his laundromat crush. Its very funny, fairly geeky, and on the Internet so of course I've enjoyed it thoroughly and have some links to share. It surprised me how many blogs that I don't usually see posting the same things telling me about it: first on Eric's blog, then The Old New Thing, and even Penny-Arcade.

Dr. Horrible's again available online via Hulu with commercial interruption.

Check out the official fan site. They link to such things as the owner of Dr. Horrible's house. He had appeared on Monster House, a reality show about remaking people's homes like Monster Car or Pimp My Ride is about remaking folk's cars, and had his house turned into a evil scientist's lab. Consequently its a perfect fit for Dr. Horrible and in return the owner appears in one of the final scenes and in the credits as the 'Purple Pimp'. Apparently the purple suit is his. Also on his blog you can find out what's happened on that big chair that appears in the show. All I'll say about that is, good thing Neil Patrick Harris wears a lab coat while sitting on it.

At the recent Comic Con some attendees took video of the Dr. Horrible Comic Con panel (video clips contain spoilers) some of which I've grouped together. Besides the videos containing the creators and stars of the musical who are all hilarious (see Felicia Day's comment on twittering) there's also some excellent bits about a possible second installment and information on the impending DVD.
