When I render a sony vegas video, I cannot see the video once the file has been rendered unless I set AVI to NTSC. If I set it to HDV 720 or greater only the audio shows up. The files are very large so I have to believe the video is there but I cannot see it on my computer. I was told that it could be a codec issue so I downloaded K-Lite codec bundle. I still have the same issue. What should I do?

I don't understand why an AVI file set to NTSC (720 x 480) will show up but if I set it to HDV-720 (1080 res or higher) the video does not show up. I wonder if I burn it to a DVD will it show up on my home stereo DVD player.

Please help.
