As I understand it, the "GRAB" function uses the DVB card's analogue 
"video4linux" interface to re-digitise the video.

A better quality solution would be to use a software mpeg-2 player, and then 
take a screen-dump from there.

You have to make sure that your software player isn't using any hardware 
video acceleration (for example, the -vo x11 option to mplayer works for me).
