After not having much luck with the last video card, I changed my video card to a device with the Philips 713x chipset
Now when I select video capture I get the following message:
failed to initialize the video capture plugin
Open driver failed
cannot create the video capture filter
I have just installed card (SAA7130 TV PCI card) with latest drivers excluding the software so Video Studio 12 pro is the only capture software on the machine
I also re-installed both card and Video Studio after doing a complete system restore and used CC cleaner to remove any residual data before re-installing
I need to use video capture within the Video Studio software as I need to use the scene detection functionality.
The reason I had to change the card in the first place is that video studio only allowed me to capture in AVI 320x240 and gave 'capture failed' errors with anything else.
