"window media player
Do you mean that you can not play windows media player files (i.e., media files that have the .wmv extension) in Ubuntu??
If this is indeed the problem simply install the "ubuntu-restricted-extras
" package from the Ubuntu Software Center or Synaptic Package Manger and you should be good to go.
You should also enable the medibuntu
repository to have access to the w32 (for 32 bit Ubuntu) and the w64 (for 64 bit) Windows codecs. See this: http://medibuntu.org/repository.php
Running that first command there from the terminal should be sufficient to enable the medibuntu repository.
Alternatively, just open the problematic .wmv file with the Totem media player (it may be listed as just Movie Player in the Ubuntu menu). This should offer to install the needed codec if you do not have it already installed.
Write back if you need more help.
I have no experience with webcams, so I can not help with that.
