dvd playback

Hi i just made my first dvd from using windows dvd maker, And i was able to
play
it on my computer, and on a sony ps2 but my Panasonic dvd player wont play
it. i tried it also on a newer dvd player that was only about $40 and it
played . I will check with panasonic,about that. But i was wondering if there
are any options when choosing to burn a dvd that i could try differently? My
files were converted to mpeg1 using a video capture device made by pinnacle
thanks Tim
