No. The card does not "suck". It works just fine in Windows Vista Home Premium 32 bit as well as 64 bit. I know because I have one and use it daily. It's a fine card as a matter of fact.
To the original poster (and possibly to Guy)
The cards are boxed up months in advance of release and, as a result, do not always ship with the latest software. Go to the manufacturer's website and download the latest drivers/software for your TV Tuner card. This is especially important if you are using the Hauppauge card. Install Vista normally, (without applying patches) and only install the drivers for the TV Tuner card through Device Manager by selecting the device and right clicking it, then choosing Properties and then the update driver option. Point Vista to the driver you downloaded, via the browse, function, then install it. It should work fine.
Anytime you apply several updates at once, and it breaks functionality with a piece of hardware, the best thing to do is roll back to the restore point you created before you loaded the patches and then load 1 patch at a time. This allows you to test if you still have functionality. That way, you identify which particular patch is causing the problem and can then decide whether or not that patch is worth loading. (not all patches are meant to be loaded)
