The Ugly Secret of Windows Media Center

Some Q&A from the Frequently Asked Questions About Windows XP Media Center Edition 2004 page:

Q. What file format does Media Center record in?

A. Media Center uses a new file format called DVR-MS. DVR-MS is an MPEG-2 file that includes metadata about the recorded program to be stored.

Q. Can the file format used by Media Center be changed? Can I edit recorded TV files?

A. No, Media Center supports only the DVR-MS file format for recording TV. It's not currently possible to edit DVR-MS files (the format used for recorded TV files). However, some third-party software manufacturers have applications that support the conversion of DVR-MS files into other formats.

Q. Can the files generated by Media Center be converted to another video format?

A. At this time, there is no way to convert DVR-MS files to another format. Microsoft is currently working with third-party software manufacturers to add support for DVR-MS files to their products.

Q. Can I edit recorded TV files?

A. It isn't possible at this time to edit DVR-MS files (the format used for recorded TV files). Microsoft is currently working with third-party software manufacturers to add support for DVR-MS files to their products.

Q. Does Windows Movie Maker support the Media Center file format?

A. Windows Movie Maker does not support DVR-MS files at this time.

So, not only can you not pick the recording format, you are stuck using a proprietary format that nobody's products, including Microsoft, even handles for editing purposes. I got one word for Media Center 2004: fuhgettaboutit.

Now. Now. Now. Don't be the FUD rucker.

Not only can you burn DVDs directly from MCE (using a Sonic Plug-in). You can also transcode into standard MPEG2.

I'm sure more will come.

Hey, man, I'm just passing on what MS says in their FAQ. But, I'm glad to hear the situation isn't so grim as the FAQ makes out. Thanks for the info!

Whoops. I didn't mean to jump on you. Some people just have a tendency to slam MSFT for everything. I just like to balance the news.com effect. ;)

Your individual-archives pages seem to be running into an IE CSS bug. It manifests itself by a disappearing page. It was a bug that I had also. Good luck in fixing it. I eventually just reworked the whole damn page.

Funny...I've generally thought of news.com and CNET and ZDNet as very pro-Microsoft, chalking it up the significant advertising dollars that Redmond throws their way. I'm no fan of Microsoft's business practices, and I think that their claims of "innovation" are pure bunk, but I do use MS products a lot (WinXP is very good and Office is definitely best-in-class).

Steve,
Thanks for the note about the IE CSS bug, but I'm not seeing it (IE6).

Of course, I never use IE unless forced to (I rely on Mozilla browsers), so I wouldn't have noticed anything even if I *could* see it. ;-)

It's a frustrating one. It isn't always there, but it is certainly there often enough for people to get annoyed by it. After enough people told me that they couldn't see my pages, I was forced to deal with it. The problem was that thousands and thousands of people just didn't say anything. :(

Just downloaded WinDVD Creator (trial) and it does recognize and record MCE files to DVD for use in regular DVD players.

Arcsoft Showbiz 2 will transcode dvr-ms to mpeg. When you import the dvr-ms to Showbiz 2 a window opens up asking to ok the transcoding. The software is an editing program, but I'm a novice to editing and cannot tell you how good or bad it is. This is a link to the simplistic breakdown of the dvr-ms filehttp://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnwmt/html/dvrfilechanges.asp

I have fianally been successfull in creating a DirectShow graph to convert the dvr-ms files to an AVI. I have done 4 or 5 several hour shows and have not seen any AV sync problems. Here are the steps and the files that I used.

Get the following files and install them:
Elcard MPEG decoder:
http://www.elecard.com/ftp/pub/mpeg/decoder/EMpgDec20.zip

Ogg Vorbis
http://tobias.everwicked.com

Divx Codec (I have the $30 pro version)
http://www.divx.com/divx/

Graph Edit
http://www.digital-digest.com/dvd/downloads/graphedit.html

Trobettworks Filter Configurator
http://www.trombettworks.com/FilterConfigurator110.zip

Start Graphedit.
File->Render Media File (select your dvr-ms file)
Insert the following filers into your graph:
Audio Compressors->Vorbis Encoder
DirectShow Filters->File writer (select your output
filename. Include the .avi extension).
DirectShow Filters->Filter Configurator by Trombettworks
DirectShow Filters->Ogg Multiplexer
Video Compressors->DivX 5.0.2 Codec

Select the Filter Properties of the
Filter Configurator
and set the properties for the DivX codec.

I used a bitrate of 500 and 1 pass quality. This results in an AVI file that is a little bigger
than 1/10th of the original file size.

Delete the Video Renderer and Default Direct Sound
device.

Connect the MPEG audio decoder to the Vorbis
encoder.

Connect the Elcard MPEG-2 video decoder to the
DivX codec.

Connect the Vorbis Encoder and the DivX
codec to the Ogg Multiplexer.

Last connect the Ogg Multiplexer to
the File Write. Now play your graph.

After it is done (it will take about the same time as the length of the show) you should be able to play the AVI file on any computer that has the right codecs installed

It is different doing this for the first time, but it gets easier, and it really gives you a first-hand taste on how movies are made!!

I dont know if any of you are having this problem, but when I try to view live tv OR dvds using media center, it tells me that I haveb a video decoder error and I should look at the hardware documentation about fixing the problem. Ive downloaded the tv tuner drivers and installed them several times and it still doesnt fix the problem. DVDs play fine with windows media player, but not in media center. Anyone know how to fix this video decoder problem?

Posted by Greg Swaney at March 8, 2004 08:22 PM

I fixed it! WHen i first was setting up the computer, I uninstalled WinDVD...big mistake. I reinstalled WinDVD and that fixed the problem!

Posted by Greg Swaney at March 8, 2004 08:44 PM

couldnt i just find some other program to record with all together instead of going through all this converting stuff?

Posted by J3SS3 at March 9, 2004 06:35 PM

I don't know if this will be of help to anyone, but I use DrDivx to re-encode dvr-ms files.

I got it working by accident, but eventually figured out how to get it to work.

Step1
Install DrDivx

Step2
Install Elcard MPEG decoder (see link above)

Step3
re-encode!

Anyway to create DVR-MS format FROM wmv or mpg?

Posted by mjs at March 13, 2004 11:11 AM

a program called dvredit was planed to convert mpg to dvr-ms but it the creator is still working on it or stoped. It converts vob files to dvr-ms. So just find a way to convert mpg or wmv to vob (Nero encode) then use dvredit. But why go mpg or wmv to dvr-ms? also dvredit lets you enter the show info for the file you want to convert. find dvredit here at http://www.thegreenbutton.com/

media files r usually recocnized by their encoding rather than file extension. i think mpeg-2 encoded file will be recocnized by most softwares supporting mpeg-2 regardless what ever their extension is

the problem i have is using the inputs om my break out box (coax,s-vid,rca) for my laptop i realize it would be best for me to go firewire to cap my camera but i already have this usb breakout box, that only seems to work for coaxial inputs

please help
