I switched video cards today in my PC. I went from a Radeon X700 to a Radeon X1300 card (both PCIe - 256MB). I normally place the preview window in Vegas 5 on my Samsung HDTV via the HDTV out on the video card (while viewing the time-line on my Dell LCD.) Worked great for the last 8 months with the X700 card - audio in perfect sync with the video. Now with the new video card, the video is behind the audio. Any ideas on how to get the new card to sync video with the audio? (I tried different preview settings in Vegas and tried different settings for the secondary monitor in the video settings on my computer.)
