Getting the Most from Your Media Center
05.01.2007
CMy
first glimpse at Microsoft's Windows Media
Center technology, during a pre-Consumer
Electronics Show (CES) briefing in early
2002, was eye-opening. There before me, I
could see the future of
TV: Windows Media Center offered live
and recorded TV functionality. Although
set-top boxes from TiVo and Replay were
pioneering
digital video recording (DVR)
functionality, the Microsoft solution was
far more interesting because it came wrapped
inside a true Windows XP-based PC. Surely, I
thought, the future of TV was one in which
TV content could be enjoyed in a variety of
places, and on various devices, whenever
desired.
Since then, XP Media Center Edition (MCE) 2005 has taken off in the market, thanks largely to some concessions and price reductions on Microsoft's part. Today, XP MCE 2005—not XP Home Edition—is the standard XP version sold on most consumer-oriented PCs. As a result, millions of people around the world finally have experienced Microsoft's premium digital-media environment. Curiously, most of these people don't actually use Media Center to interact with their TVs—one of the previously mentioned concessions is that Microsoft doesn't require PC makers to include TV tuners on Media Center PCs. And that's too bad, because Media Center's TV experience is top-notch.
Like TiVo, Media Center lets you watch, pause, and rewind live and recorded TV. (You can also fast-forward recorded TV, of course.) If you have the right hardware—dual TV tuners and two or more TV signals—you can even watch live TV while Media Center records a second TV on a different station. And with over-the-air (OTA) HDTV hardware, you can record HDTV. The Windows Vista version of Media Center, shipping in Vista Home Premium and Vista Ultimate on January 30, 2007, will also support cable-based HDTV signals, although only through new CableCARD-based PCs. Therefore, you'll need a new PC to enjoy this capability: There won't be any upgrades to support this functionality with XP MCE 2005.
That said, there's still a whole world of TV-based entertainment to enjoy, even if you decide to stick with XP MCE 2005. Because content is all stored on a normal PC, you can copy it to portable devices, stream it to other TVs in your home, archive it on a home media server, and—with the right tools—even convert that content into more space-friendly formats. Users with Windows Mobile-based PDAs and smart phones can even sync that content with those devices. When you think about it, this kind of functionality is the ultimate example of time shifting, because you can also device-shift to use a device that's more at home in your car, an airplane, or other places. It's what DVR is really all about.
Moving
Content Around Your Home
Microsoft has yet to come up with a
PC-to-PC solution for sharing Media
Center-based content (apparently that
would be too logical), but the company
has put various solutions in place for
streaming Media Center content to other
TVs in your home by using various
devices. Current Media Center owners can
choose between an original Xbox running
the Media Center Extender program disc,
a hardware-based Media Center Extender
from networking companies such as
Linksys, or the Xbox 360, which includes
Media Center Extender functionality
built in.
Functionally, the Xbox 360 is going to give you the best experience: Its Extender software completely duplicates the look and feel of Media Center, whereas the versions in the original Xbox and hardware Extenders are a bit toned down because of the limitations of those devices. For example, you don't get the nice animations during photo slideshows.
Whichever Extender solution you use, you're going to need a fast 802.11g-based or 802.11a-based wireless network or—better yet—a wired network (100Mbps or faster).
Taking
Media Center Content on the Road
If you've got an XP-based notebook of
any kind, you can simply copy recorded
TV shows (which are stored in a
proprietary Microsoft format called
DVR-MS) to your notebook and play them
in Windows Media Player (WMP)—and if you
have a Media Center-based notebook, you
can of course use that application. That
solution works fine, but DVR-MS files
are humongous, occupying over 1.5GB of
space per 30 minutes of content. That's
right: A two-hour movie takes up over
6GB of space (and takes an eternity to
transfer across your network). If you
know you're just going to delete the
recorded TV shows after you've watched
them, the huge file sizes might not be a
concern. But if you're running low on
hard disk space or would like to archive
TV shows, you're going to need another
solution.
Sadly, the market for DVR-MS-compatible video-editing suites is smaller than you might expect, and although there are some free solutions, I've never found one that works reliably. If you don't mind spending the money, the $99 TMPGEnc 4.0 XPress is excellent and works with DVR-MS format. Or, if you can wait until Vista, the version of Windows Movie Maker (WMM) that ships free with that OS can also convert DVR-MS files to smaller versions.
There are a variety of formats to choose from when you’re transcoding (or converting) from DVR-MS, but I've found that Windows Media Video (WMV) format offers excellent file sizes, quality, and compatibility. (These files will also work with all Extender types, notebooks, and other Microsoft-oriented devices.) How good is the compression? A WMV file that is visually indistinguishable from the DVR-MS file will occupy about 280MB of space. That's right: It's less than a fifth the size. Of course, transcoding takes time. That's one of the reasons TMPGEnc 4.0 XPress is so nice: It can run overnight in batch mode on multiple recorded TV shows.
You can also use these solutions to create content that will run on smaller devices, such as portable media players (e.g., the Microsoft Zune), Portable Media Centers (e.g., the Toshiba Gigabeat), or even Windows Mobile devices. Because these devices have small displays, you can often cut down dramatically on file sizes yet again: A 30-minute Zune-oriented WMV file (at 320 x 240 resolution) typically takes up about 150MB, for example. WMM and TMPGEnc 4.0 XPress both ship with profiles oriented toward various screen sizes and device types.
Making
Movies
If all this talk about transcoding and
editing movies sounds somewhat daunting,
you can also burn DVD movies of your
recorded TV shows: Virtually all Media
Center PCs include that capability out
of the box. All you need is a stack of
recordable DVD media and you're good to
go.
Trouble
in Paradise
As always, there are a few caveats to
this technology. First, because TV
stations can protect their content by
using a technology called Broadcast
Flag, it's possible that some
transmissions can't be transcoded into
smaller WMV files or even played on
other PCs. Today, HBO is the biggest
offender: All the content HBO provides
through its HBO and Cinemax pay-TV
channels is protected with Broadcast
Flag, so although you can stream this
content to other devices in your home,
you can't copy it to other PCs or
transcode it to other formats. In the
future, CableCARD-based
digital TV and HDTV signals will
suffer a similar fate. Still, the fact
that you can move this content around as
much as you can now is somewhat
impressive, and if you're truly
die-hard, you can even edit out
commercials before transcoding. Not too
shabby.
