1. Have you captured the video from your camera to your hard drive?
2. Is it DV or HDV?
3. What shows up in the Program window? Black or Offline?
3. Will the clip play in Windows Media Player?
4. Will Premiere display other video, like the WMV samples in My Videos?
A wild guess; You captured only audio. At the top of the “Logging” tab in the Capture window is a drop down menu…Capture…(What).
