DVD play problem on X30 + Wi-FI solution.

[dainova]

Hi,
I can't play DVD on fresh XP'Pro install (from retail) using any player (let say I play the same DVD on VLC player on another laptop, but can't play it using exactly same VLC on my X30). I can see the drive and do audio though. Device Manager looks fine , is there any special driver reqired, that could be on restore CDs?
my DVD in slice-dock.

also:
I did my homework learning how to intall miniPCI on my X30, but still not clear, how I can check does it have antenna built in or no?

+ is LAN/Modem also on miniPIC ? If yes, so probably I don't have a choice to make it without scrapping LAN or Modem.
Or I hope it somehow built in in other way ?

Will appreciate your help.

Here is my sys:
