Since it's composite video, "ViVo" (video in/video out) versions of a graphics card would work just as well as the full AIW tuner capability.
Also depends, what buses are available in the PC - current model with PCI or old wreck?
I'm also thinking of a "DVD maker" kit that included a USB based capture device.
The output description would seem to match standard, line level composite in NTSC format, the sort of thing that would plug into a video recorder.
Only problem I can see, since it's not USA, is NTSC the normal standard there?
USA - NTSC "Never The Same Colour"
UK - PAL (Phase Alternation by Line) ... phase error in the USA system causes colour shift, while phase error in the UK system is compensated.
France - SECAM
Other areas vary, though the usual choices seem to be NTSC or PAL with different sound subcarrier.
