Autoplay not recognizing movies properly

[boe]

I have nearly identical computers - both running Windows XP Pro - SP2 - all
the latest patches. Both running on P4 2.8 GHz PCs. Both with the same DVD
drive with the same firmware.
When I put the DVD in one computer it pops up with the what would you like
me to do - play, explore, windvd etc.
When I put the same DVD in the other computer it just sits there.

I went to the autoplay properties of the drive and selected DVD and set to
restore defaults - nothing happens after I reinsert the DVD. I set it to
WindDVD - nothing happens.

If I manually open WinDVD I can play the movie on both computers no problem.



I noticed when the DVD is in the first computer ComputerA (the one that
autoplays properly) If I select My Computer it lists the title of the movie
next to the drive letter.
If I put the same DVD in the second computer ComputerB it shows that it is 4
GIGs but nothing more and if I click on the drive it shows me the contents
of the DVD AUDIO_TS and VIDEO_TS If I select the VIDEO_TS I can click on
the files and get the movie to play with WinDVD - but I want it to autoplay
without doing the extra steps.

Not sure what I need to change for it to recognize the DVD in the drive as a
movie so it autoplays.


Thanks
