Robert,
   I tended to agree with you but there is a bit more to the 150 than
that. I found that using the C key I could switch between tuners. On
screen I see:

1: Tuner 0
1: Tuner 1

Each tuner can tune to a different channel, and each tuner remembers
what channel it was on, so when I hit C I go between channel 2 and
channel 28.

That said it could all be smoke and mirrors. Maybe there is only a
single tuner and maybe software is remembering which channel to show
me. I don't know.

The important issue would be setting it up to use both and then seeing
if the MPEG encoder will encode both at the same time. Even with two
tuners if the hardware encoder only works with one then it's not of as
much value.

I only brought this up since the Hauppage page says the 150 replaces
to 250 but my 250 doesn't have this Tuner 0/1 feature. (Caveat - 250
running with ivtv 0.2, 150 running with 0.3.3k.)
