I've always wondered if using a high end Upscaling player with a PC capture card would yeild better results for the GOUT. Running 1080p from a Toshiba XA2 or an Oppo seems it could be a better option than software upscaling.

I've looked into this and you'd be surprised by how well FOSS solutions hold up. The algorithms used by many proprietary upscaling chips have to cut a lot of corners in order to produce results in near-real-time. They can't afford to do what, e.g., NNEDI3 does.
