There honestly isn't much more the pcHDTV folks can do on the driver side to
improve performance. The card just isn't that complex. It tunes into a
broadcast mpeg2 transport stream and dumps it to disk. The mpeg2 file is an
mpeg2 file is an mpeg2 file. The vast majority of the optimization has to
come on the playback side. While better decode algorithms definitely help, I
think the biggest gains are to be had from getting GPUs to bear more of the
burden.
