I don't have the full version of the ATI tv wonder and I don't have any problems with freezing any more. You asked what I did? I followed their directions. But to summarize things ati asks to ignore the multiple card message during installation. After installation do not reboot the computer. Right click on my computer and go to properties. Hit the hardware tab and click on Device manager. Another window should pop up with the device property. You'll see other devices listed there with a question mark inside a yellow circle or something along those lines. Uninstall those two multimedia devices. Restart your computer and when asked for drivers point it to where you decompressed the files, i.e. c:\MMC-TVWonder. Click ok and you should get 5 prompts asking for an ok to install the drivers. I hope that helps.
