Update Rollup 2 for Windows XP Media Center 2005 is now available on Windows Update!

As of 8am Pacific Standard Time this morning, Update Rollup 2 for Windows XP Media Center Edition 2005 is now available for download.  It is being announced at the Digital Life conference in New York City this morning.  This new update rollup will be offered as a recommended update on all computers running Windows XP Media Center Edition 2005.

There is a lot of cool stuff included in Update Rollup 2 (in fact, naming it an "update rollup" doesn't come close to doing this product justice).  Here are some of the highlights:

  • Improves the Media Center Extender experience - Media Center will automatically recognize when a Microsoft Xbox 360 is connected to the network. Additionally, Media Center now prompts you to install the software components that Media Center must have to support the Media Center Extender functionality of the Xbox 360
  • Additional tuner support - this update adds support for a 2nd Advanced Television Systems Committee (ATSC) tuner card on U.S. versions of Microsoft Windows XP Media Center Edition 2005; overall, Media Center now supports up to two ATSC tuner cards and two National Television Systems Committee (NTSC) tuner cards
  • DVD changer support - Media Center will now offer gallery and details views for DVDs loaded into several upcoming changer devices (up to 200 disks)
  • Support for DVB-T radio in regions where DVB-T radio is broadcast
  • A configurable optimization option to make sure that your Media Center computer continues to run smoothly
  • A new nonlinear zoom mode for widescreen TVs
  • Improvements to the process of burning DVDs in Media Center
  • Improved reliability - add-ins are now hosted in separate processes so they will not cause the entire Media Center process to crash if something goes wrong
  • Many bug fixes to address issues from previous releases

Update Rollup 2 requires that the .NET Framework 1.1 and 1.1 SP1 be installed.  Windows Update will automatically include these packages on computers that need them when you choose to install Update Rollup 2 via WU.  One note here - the issue I described here regarding .NET Framework hotfix 886904 will affect Update Rollup 2 if you try to install on a machine that has .NET Framework 1.1 and KB886904 installed but don't yet have 1.1 SP1 installed.  If your computer is in this state and you see Update Rollup 2 fail to install via Windows Update, make sure to uninstall KB886904 using Add/Remove Programs and then try to install Update Rollup 2 again.

In addition, there is a small set of additional fixes that we were not able to get ready in time to include in Update Rollup 2 before our final sign-off, but that are now ready for download.  After installing Update Rollup 2, you will see an additional update (KB908250) available for download as a recommended update on Windows Update.

I strongly encourage you to install both Update Rollup 2 and KB908250.  Let me know if you run into any issues or have any questions as you try to install it and start using it.

  1. Have you seer this:

    I got the same message too. After clicking OK, a second message was there.

    "Component Registration Failure.

    Some of the files needed to play radio or video are missing or corrupt. Media Center component registration may have failed"

    My Tv no longer works.

  3. Ian and Kevin – I have posted a set of instructions at http://blogs.msdn.com/astebner/archive/2005/10/16/481689.aspx that describe how to gather MCE Update Rollup 2 setup logs and send them to me. Can you take a look at those and then contact me and I’ll try to help figure out how to get your machines back up and running?

    Ian – I also found your blog post at http://spaces.msn.com/members/iandixon/Blog/cns!1pG33U4bh6jzLG6yE4ZZG2Bg!920.entry and posted some additional suggestions that will hopefully help.

    Non-linear zoom ROCKS! My blog entry on that:


    Also, what does "A configurable optimization option to make sure that your Media Center computer continues to run smoothly" mean? I found it in the settings, but what does it DO? defrag? Find underpants gnomes and profit?

  5. Kevin D says:

    Aaron, I read your weblink about sending the logs. However, I rather a novice when it comes to this and have to say I don’t know where to find them! And when I do, I guess I can just copy and paste them into an email?

  6. Kevin D says:

    I just finished doing a System Restore. I had done a bunch of other updates on the same day as the Rollup and wanted to make sure they were not messing things up. It is indeed the Update Rollup that is causing my problems. I have all the other updates installed and my Media Center works fine. Once I do Update Rollup, I get the above errors when I use My TV. I did another System Restore to just before the update so I can still use my Media Center. Hopefully this update will get fixed soon.

  7. Hi Kevin – I just posted a workaround to a common issue I’ve been seeing. It is located at http://blogs.msdn.com/astebner/archive/2005/10/18/482472.aspx. Can you try the steps listed there to look at your %windir%medctroc.log and see if you are hitting the issue described there, and if so, can you try the workaround listed there?

    Hope this helps!

    Possible culprit … I had the exact issues described in this thread. I fought it to no avail until I found this. Last night I uninstalled Rollup 2, and uninstalled 2 Hotfixes to .Net. I then reinstalled .Net 1.1. At that point MS Update wanted me to apply 2 updates. The first is an update to .Net 1.1 SP1 BUT the other is an update to .Net 1.0 SP3! I applied the first and not the second, this latter one had been installed by me a while back. I then reinstalled Rollup 2 and voila everything works perfectly. I suspect the .Net update to 1.0 is the issue but I am loathe to experiment to prove it.

  9. Hi bmgarelick – Thank you for posting your experiences getting Update Rollup 2 to work correctly. I’ve been looking into this issue since it was first reported, and I don’t think that the hotfix for .NET Framework 1.0 SP3 is the culprit in this case. That hotfix does not update the file that has been shown to cause many of these issues (%windir%system32mscoree.dll).

    The cases I’ve seen so far that have been problematic involve performing an OS reinstall over the top of the existing OS and choosing not to format the partition as part of this reinstall. I suspect that System Restore may cause some of the issues as well but I haven’t been able to definitively prove that yet.

    Please don’t let this post die! I had the exact same problem when I installed Update Rollup 2. I uninstalled the update and can watch TV again, but am awaiting a solution so that I can re-install. Thanks.

  11. Hi gurs – can you please send me the log files that I listed in the blog post at http://blogs.msdn.com/astebner/archive/2005/10/16/481689.aspx so I could take a look? I have been able to resolve several of the issues listed in the comments for this post so I’d like to look at your log files as well to see if I can help with your scenario so you can reinstall Update Rollup 2 successfully. You can send the logs to aaronste@microsoft.com.

    Spoke too soon. I thought I had the problems resolved but it turns out that although my extender seems to be OK, my monitor isn’t. I get a black video screen when I change the channel and the video freezes if I change the window size.

    Does anyone know if there is a fix coming from MSFT that will unravel whatever Rollup 2 did and then properly update the system?

  13. Lee says:

    Can you go more into what "Many bug fixes" is? I am a MCE developer and a bit worried about possible incompatibilites.

  14. Nick Spacek says:

    So I went through the log looking for warnings, and found one while it was trying to register DLLs and COMs. It was with ehrecvr.exe. When I went to %windir%ehome and ran it, it gave a missing DLL error. Once that DLL was replaced, everything works fine!
