Trying to achieve the above to transmit over the web.

In webcam Preferences, I can choose my webcam software or my TV card (Vaio) as input device. Choosing thr latter does stream the TV prog through vid cam. However if I use the Vaio software to show a vidoe file, the webcam wont follow suit.

Is there any hardware/software route to get it to show a vid file? There is a single phone type socket in the back of the webcam but you don't seem to get video-out plug --> phono.

Any suggestions gratefully accepted.
