I am desparate! I need some answers or solutions.

HERE IS MY STORY:

My last computer had Windows 7 on it and it came with both Windows Live Movie Maker and Windows DVD Maker.  Back then everything worked great. I was able to burn my movies that I created in Windows Live Movie Maker to DVD and they looked and played normal on my TV.

Now I have a computer that has Windows 8. Windows Live Movie Maker came with it but I had to purchase Windows DVD Maker.

Here is what I did:
I added my file to Windows DVD Maker.
I clicked on preview and it looked normal.
I inserted the blank DVD.
I clicked on start and it burned the DVD.
I put it in my DVD player to play it on my TV and it looks very distorted. It does not look like me. Also the picture does not fill my screen.

Also these same videos I posted to Youtube look normal. I just haven't been able to burn them to a DVD.

I have repeatedly sent emails to support and nobody will answer me and acknowledge my problem. It has been three months and I can't do anything. Can someone out there give me some help. Thank you.
