Windows 7 Media Center Lags horribly

[HunterJoe]

Hi all,

New to the forums but not to Windows. I just recently built a new system as an upgrade from HP Elite m9340f Media Center PC. I bought a new Mobo, Video Card and PSU. I used the HDD, RAM, CPU, DVD, and TV Tuner card from the HP in the new build.

My current specs:
Gigabyte GA-EP45-UDP3 Mobo
Socket 775 intel Core 2 Quad Q6700 2.66Ghz
8MB DDR2 RAM @ 800 Mhz FSB
ATI Radeon HD 5770 1GB GDDR5 PCIe x16 (CCC 9.11; Driver Version 8.671 - 11/04/2009)
Hauppauge WinTV HVR-1800 (Model 7800, Combo ATSC/QAM) connected to a PCIe x1 slot (Driver version 1.41.27195 - 7/14/2009)
Win 7 Pro 64bit (Clean install)

Everything works great, except Windows Media Center. I have installed the latest drivers from Hauppauge for Win 7, but when I run MC, the video lags my entire system horribly. Every few seconds the video stops then starts up again, and if i run MC as a window and not full screen, then as my mouse moves around the screen it jumps and skips too. The video performance suffers considerably. I have searched the froums here and on the net, but most of the time this problem is mentioned there is no solution given for it. If anyone has any ideas as to how to fix this it would be appreciated.

Joe.

1. Choose Start > Control Panel.
2. Double click Personalization and select Display Settings.
3. Click Advanced Settings.
4. Click Change Settings on the Troubleshooting tab.
5. Move the Hardware Acceleration slider to None.
6. Click Apply and then click OK to accept the new setting and close the dialog box.
7. Click OK to close the Display Properties dialog box.
8. Restart Windows.

Change Settings is greyed out, I guess my drivers don't allow me to change the settings. Is there a way to do it in the ATI Catalyst Control Center that you know of?

The TV tuner card could be causing a conflict with the video card. I have seen it many times. That was to disable DirectX hardware acceleration - it can't be done through CCC. I would look into replacing the card or buying a different tuner card.

You could also try moving things around internally by opening up the case as a last resort type of thing. I can't say why, but you gave us somewhat of an answer already when you said you had no slowdown when you used an NVIDIA card with the TV tuner. So its probably a conflict between the two.

Good point. In the Mobo manual the slots are numbered PCIe_x1_1, PCIe_x1_2, and PCIe_x1_3. The tuner card is currently in slot 1, but if moved to any other slot Windows dosen't even recognize it. I don't know if slot one NEEDS to be filled first or if there is something wrong with the Mobo, either way moving it isn't an option.

Replacing the video card... I just bought it... the tuner card my be a better option. I'll do some research into tuner cards that work with ATI video cards.

As a temporary alternative, you can get Internet TV from Netflix on Media Center.
