ConvertX2DVD DVD does not play

I loaded up an AVI…it encoded and burned no problem. I cannot play the DVD thru Win media player or the Nero player. I burned to DVD+RW.
Any help will be appreciated.
Thanks much
(I would include the log but cannot see how to copy it)

Windows Media player can not play DVD unless you have MediaCenter edition or some DVD-player program installed.

Gave up my Media Center PC.
I also tried to play it with Nero which also did not work. Should Nero work?

I tried the RW in my standalone player and it played beautifully and the quality was outstanding. Thank you for pointing out that Win MP won’t play DVD.
