I have solved one of the problems..the capture card is now working well..when I took the hard drives and the TV capture card out of my old machine and put them in the new one, I should have completely cleared out everything from the old TV card installation in Windows and in the registry (There was some great help on the Modular Technologies website on this). Once I did this, reinstall and tweaked one setting in the registry (Apparently, this type of card does not like living alongside a great many graphics cards-including mine!!), it running jyat fine..

Still need some help on the other points though
