What did they say? This version of Sony Vegas do support HD.? Did the PVR come with any software at all? I am really a stranger to HD video but I thought maybe these might be good question to ask and learn a bit.
I just bought an HD PVR and have recorded videos just fine, they playback in Windows Media Player perfect. But when i open the file to sony vegas, it only preview/renders the top left part of the video. And its really zoomed in, ive try event/pan/crop. Ive tried to lower the HD settings on my Xbox and it zoomed out a little bit, but its still only part of the video.
