That card is only MPEG1, which means unacceptable (for most applications)
video quality.

There are plenty of options if you don't want real-time MPEG2 encoding,
including using DV over firewire, MJPEG, raw AVI, etc.  The problem is the
storage requirement and the time required to encode as MPEG2.  If you are
wanting to do a PVR application or live MPEG2 streaming there is really no
other choice but to have a hardware MPEG2 encoder.  Even for things like
DVD authoring, the time required to encode to MPEG2 is prohibitive as well
as the space requirement.
