Install Questions: Associate with suppoorted files

[wanchan]

I just got my BSPlayer Pro 1.02. While installing, I got a component selection question asked by the installer: Associate with BSPlayer Pro suppored files.
I certainly do not want to have BSPlayer "steal" file extentions from other apps, and then end up not being able to playback anything if I decide to unsinstall using BSplayer. Attached the screenshot of installer window.

Questions:
If I choose to install "associate with BSPlayer supported files", can I still unassociate once it is installed?
If I do not choose to install "associate with BSPlayer supported files", can I still associate BSPlayer files under something like Options?

Thanks for advising.
