I wish I'd came across this FAQ before I started re-installing my Hauppage PVR250 card - merely running the uninstaller, re-booting, re-installing the current card driver and then the application ain't good enough! The page on their site doesn't seem to be linked off of the support section and has a couple of dead links - the link to the PVR application (for example) - you can snag that file from their Digital Asia site.
This aside I think it is a killer product - I'm increasinly using it instead of my VHS.
