Gregg, How would this work for digitizing Laser Discs? I have a handful of discs which have never been released on DVD or Blu-Ray and it would be nice to get the content in the digital domain. I have no idea about the whole time base correction aspect… Is it required?
There are likely better modern solutions, but I am not sufficiently motivated (too lazy) to look.
