Windows 7 Media Center w/ Hauppauge 1800 MCE

It seems like you are experiencing issues with your Hauppauge 1800 MCE TV tuner card in Windows 7 Beta build 7000, specifically related to distortion and interference lines in the media center. This could indeed be caused by driver compatibility issues. Here are a few steps you can take to address this problem: 1. Check for Driver Updates: - As you mentioned, in Vista 64, you received a new driver through Windows Update. It's a good idea to check if there are updated drivers available for your TV tuner card that are compatible with Windows 7 Beta build 7000. Visit the Hauppauge website or check Windows Update for any driver updates. 2. Compatibility Mode: - You can try running the driver installation in compatibility mode. Right-click on the driver installer, go to Properties, then Compatibility tab, and select an earlier version of Windows (like Vista) to run the driver installation. 3. Manual Driver Installation: - If the automatic driver update doesn't work, you can manually download the driver for the Hauppauge 1800 MCE TV tuner card from the manufacturer's website and install it in Windows 7 Beta. 4. Beta Software Limitations: - Keep in mind that Windows 7 Beta build 7000 is a pre-release version, so there may be limitations or compatibility issues with certain hardware devices. Updates and fixes are typically released in subsequent beta builds or the final release. 5. Community Forums: - You can check online forums or communities related to Windows 7 Beta to see if other users have experienced similar issues with your TV tuner card. You may find workarounds or solutions shared by others facing the same problem. Before proceeding with any changes, ensure you have a backup of your system or important data.
