Quite correct, but it supports it only as a "dumb" frame-grabber card  
- the Video must be compressed/encoded by your CPU.

The commonly-used PVR cards have a hardware encoder on the card so  
their output is an MPEG stream, thus requiring no CPU power to encode  
the video.

So as long as you don't try and use the card for NTSC on a low- 
powered machine it will work.
