Bug on DVD playback

[grendizer]

Sorry I don't want to mess with the Nvidia settings just for a screen cap.

Playing more DVD's, I can see that problems also occur in the DVD menu screens. Some menus choices (like "play movie", "select audio language") are difficult to click. It seems like the clicking area is very small compared to the clickable text. This problem does not occur on WinDVD with the same menus.
And, as I said, clicking is completely disabled on DVD menus displaying thumbnails of pictures (that you click to display them full screen).
Another thing I noticed is that in WinDVD7, when you pass the mouse above a clickable text or picture thumbnail, the mouse pointer turns into a hand icon, but in BsPlayer 2.0, it stays always the usual arrow icon.

Also, I want to know which DVD codecs does BsPlayer 2 uses. External? Internal? Developped by Webteh or using an existing installed DVD codec?

Thanks

So far my tests are with:
Tron Double DVD Region 1
Lord of the Rings Pt 1 Fellowship, 4 DVD Edition Region 1
