EDIT – up.ht For some reason they removed the old drivers from their website, so I uploaded the folder from my downloads to upput. It was a problem that I struggled with for a few hours until I found a forum post with this information. There wasn’t a video showing this on YouTube so I thought I’d be a hero and upload it. For many people, when inserting a HD PVR clip into the Sony Vegas timeline, the application will freeze and stop responding. This video will show you how to fix that by simply backdating your drivers to version 1.5 instead of the current version. You can also try using Vegas Pro but that didn’t work for me.
