The CPU load doesn't seem high at all especially if this is a software based
DVB card. Are you in fact using the "nvidia" driver listed in your
xorg.conf file?
If your using the "nv" driver this very well could be it. Also be sure to change
your maximum resolution settings to 720x480 NTSC or 720x576 PAL in recording
profiles.
