Media Center & Tuner Problems - Crashes & Errors

Hi guys,

I was wondering if you could help me with Meida Center. I have Media Center 2005 with the rollup and have just installed my TV tuner (Hauppauge HVR-1100). It was working fine on its initial install, however I rebooted my PC and now my tv tuner has malfunctioned according to Media Center.

I installed the latest drivers for my card and my graphics card and now it says my tuner isn't installed and everytime I try to run Media Center I am getting an error box for the "Media Center Receiver Service".

I have been testing Vista and it works fine on there and it DID work fine on this version of Media Center until something went wrong :(

Can someone help me? I have no idea what to try. I have reinstalled my old tv card drivers and reinstalled the new ones (following Hauppauge's instructions to the letter) but still no Joy....I am running out of things to try.

Any advice?

Thanks,
MOZ

Are you sure the "latest" drivers are for MCE . . if not, uninstall in Device manager, reboot to let Windows "discover" the card and then guide XP to the original driver cd

Yeah the latest drivers are from the Hauppauge website and say that they require "Windows XP Home/Pro/MCE 2005 " (http://www.hauppauge.co.uk/pages/support/support_dvb-t_wintv.html)

I have just tried reinstalling the drivers from the cd setup application and again by manually finding them and still nothing. I am a little closer to finding the problem though (i think). I have noticed that it is the "Hauppauge WinTV 88x DVB-T Hybrid Tuner/Demod" device driver that is causing the problems. The driver box comes up saying an unknown device has been found...however all the other Hauppauge devices come up with "hauppauge xxxxxxx has been found".

I have also installed the WinTV 2000 application and it manages to scan the analogue signals in the UK fine, however the programme crashes when it tries to search digital channels....which would indicate the digital (DVB) part of the driver "set" is causing the problem.

Any ideas?

Thanks,

Starting with Microsoft Windows XP Media Center Edition (MCE) 2005, a process (ehrec.exe) runs at all times, monopolizing the tuner device on the system. This will prevent any program other than MCE, including Beyond TV, from using the tuner device, resulting in no picture or sound during the "Test" section of the Setup Wizard. The solution is to disable the service responsible for starting the "ehrec.exe" process. Note that this does not occur with versions of MCE prior to 2005.

1. Navigate to CONTROL PANEL --> ADMINISTRATIVE TOOLS --> SERVICES.
2. Find the "Media Center Receiver Service" in the list; right-click on it and select "Properties."
3. On the "...properties" window that appears when you do so, find the "Startup type:" entry on the "General" tab. Set "Startup Type" to "Disabled” and hit APPLY.
4. Now reboot the system
You should now be able to use capture software other than MCE.

Note that you can also disable the "Media Center Scheduler Service" if you wish, but that only preventing the "Receiver Service" from starting is necessary.

I *want* to use Media Center as I have my XBOX 360 setup as an extender to stream channels to my TV. :)

I am still having problems :(

I just did a fresh install of Media Center 2005. I installed my graphics and audio drivers and then my TV Tuner (using the setup program inside the MCE driver pack: http://www.hauppauge.co.uk/pages/support/support_new_mce.html). I then installed the MCE 2005 Update Rollup 2 and the April 2006 & July 2006 rollups. After restarting numerous times to install everything I finally tried using Media Center.

I went through the setup no problems and the channel scan found all the digital channels available. I thought "great, finally it's working". But I went to Live TV and it turns out that it isn't :(

I am still getting the "Decoder Error" message when trying to view live TV and I have checked the event viewer and it is showing:

Error: Media Center Receiver
TV tuner malfunction. (0x8000ffff) Hauppauge WinTV 88x Tuner

As soon as I restart my PC that even gets logged - its like MCE doesn't like my card....however I have had it working in the past with this version of windows and these drivers!!!

Any ideas guys? I have recenlty updated my motherboard, could that be causing some problems?

I have checked Device Manager and everything is fine - not a single unknown or conflicting device :(

What can I do now??

Thanks,
MOZ
