Sampling video well is not a trivial task, which is why whole chips have 
been designed to do the job. I have worked on a commercial product that uses 
the TVP7002 and then processes the output in an FPGA. Even then, the TVP7002 
has a whole host of configurable registers that need tweaking for each 
application.

A few years ago I was playing around with it during development and added a 
video mode for the Coco 3 RGB output and got a very nice result (I've got a 
photo of it somewhere on my machine at work). More recently when developing 
Lode Runner I fired it up again but the unit I had wasn't configured 
properly - I've been meaning to dig out the source and get it up and running 
properly for Coco and Amiga. The really nice thing about that product was it 
could upscale to 1080p and also adjust the aspect ratio.

Good luck - great progress for 3 days!!! :O

Regards,
