OK so that's looking like a bit of a non-starter then... I was hoping 
that, at least logically, all capture cards (and their controlling 
chips) do the same job, ie deliver video input to the system, therefore 
it would be a *relatively* simple job of interpreting what the Windows 
driver was producing and feeding that to something like V4L2.

Seems more complex than I thought.. ho hum... I'll *try* running 
Pinnacle Studio via WINE and see *if* that captures.  I'm not holding my 
breath though as I think it will be a pointless exercise, other than 
losing a couple of hours I'll not see again.

Thanks for the input Robin and Grant :)

Kind regards,

Julian
