Software Based DVD Upscaling

[dustybin303]

Is it possible for a windows / linux software based DVD player to feature 'upscaling'? Or can this effect only be achieved via 'hardware' ?

Computer solutions always scale unless you are outputting at the exact same resolution as the material itself.

All software players will use the graphics hardware for scaling as a matter of course. If you use ffdshow in conjunction with zoomplayer or Theatertek you can use software scaling rather than the hardware or even a combination of both.

There is a mountain of posts about this.
