Perhaps I wasn't clear. The downloaded (transferred) file (via TIVO desktop) shows the first 30 minutes as black screen w/no sound when loaded by VideoRedo. After 30.00 minutes the balance of the video seems intact. This is before resaving as .mp4. Tried running Quickstream fix with no luck. Rechecked that the file on the TIVO still plays normally. Retried transfer with no change.Is the original file OK?
