Probably not. In DVswitch it would be. DVswitch is for live use with two 
live video inputs and a VGA in. We don't include it by default, but do 
have it in our extra SW loader because it seems to be about the only live 
video switcher out there. I need to install that and look.

I will buy another web cam.... they are down to $3 these days and 
look way better than the $30 one I bought not too long ago. I am thinking 
that the kdenlive project settings may need to match the camera for it to 
work.

With regards to the VLC/Mplayer thing. There are two very strong 
followings for these very feature rich players. Using the default 
xfce/gnome/kde player is probably not tha best idea for someone who is 
actually using Studio for video creation. Mplayer gets loaded by default 
because a lot of the libs come from there, but there is no GUI included. 
It seems to me we have been down this path before and found that people 
who create video load their machine up with more than one video player and 
try to at least cover all the libs used to play video to make sure their 
video will work for "everyone". (probably have a win machine to try that 
too). I find just downloading a video to play I often end up trying out 
more than one player to find one that works right. Generally it is an 
mplayer based player that works.
