I would strongly avoid the digitizing process if you can. If it is
acceptable for you to work with digital (DVI/HDMI or Displayport), I would
recommend that. The process of correctly digitizing an analogue video signal
is hard to get right because finding the correct sampling frequency and
phase is difficult and often a manual process. Some of the problems you will
meet (especially at higher VGA resolution) are:
-sampling frequency can not be directly decided without visual trial and
-digitizing phase is cable length sensitive
-bad SNR (pixels are not square at analogue level. Transmission lines are
more critical than for analogue viewing).
