I believe you are making this more complicated than is necessary.
Under Windows95/98, making the assumption one of these is your
operating system, you are not required to do anything. The software
interacts with the necessary hardware automatically to perform the
function required.
I have a PC here on our network the contains an ATI Rage Fury Pro
32mg video card as the primary video card. The system also has a
STB PCI/TV card for television and video capture.
The ATI card is attached to a monitor and the 54" big screen TV for video
output. The data in the PC is displayed on either the monitor or the TV
set.
The STB TV card is attached to a TV cable input and jacks for the camcorder.
When, I turn on the TV application on the PC, it will output cable TV or the
camcorder to the monitor and the big screen TV. I can turn on the video
capture software, such as Asymetrix Digital Video Producer v5 and generate
video captures or still image captures. I can then edit the video captures,
add titles and special effects. Once the video is to my liking, stored in an
AVI file on the PC, I can play the video on the TV set and record it with
the VCR to video tape for distribution to friends and family... or generate
still images, such as JPGs or GIFs for use on our web site. This all sounds
very elaborate, but the truth here is that it is only a matter of adding a
TV card to an existing PC and the proper cabling. Anyone can setup
an in house video/image editing studio for a small investment. I will
also mention that you should have 128mgs of ram or more, as well as
a 450mhz processor or better for peak performance.
The long and short of this is that the software recognizes the hardware it
requires and uses it. You are required to do nothing manually to indicate
which device handles each chore.
