I would be very happy if someone can help me with ths issue.?

I have a sony handy cam DCR-TRV 33. It works with tape. I'm trying to transfer the video from the handy cam to a DVD but I'm having a little proplem. I installed all the software needed. I follow all the instruction to create the video. The computer tells me that." YOUR VIDEO IS SUCCESSFULLY CREATED. But when I tried to play it back on the computer or dvd player it tells me that the video cannot be detected. Please help me. What wrong I'm I doing?
