DVD wont play. error from DVD player says "there is no title"

I recently upgraded from vista to Win 7. I’ve been burning movies with no problems until the move from vista to win 7. Everything seems to burn just fine, but when the DVD is loading on a DVD player it just stops and I get an error message that says “there is no title” when I push play. The DVD will, however, play on the PC that burned it.
I use DVD shrink and Ashampoo Burning studio with no problems 'til now. I even tried to burn an older file that worked previously and it did the same thing.
Help. I’m baffled.

How are you burning your movies?
are you burning a movie DVD (like sold in stores) or a data DVD (a DVD with your video files on it)? If the latter, what is the format of the files you’re burning (container, video codec, audio codec)? Is your standalone DVD player DivX-certified?

What brand of your dvd player?
what type of your dvd disc?
Is it ompatible？
