Footnote. I thought, maybe I'm supposed to create a second "lineup"
on datadirect, so I tried under the same login account. It won't let me
create 2 lineups, both from the same signal source, but with different
channels. Since both the
pvr250's and the pchdtv use broadcast channels, I'm still stuck.
