My understanding was that there was an interesting side effect of the
multi-record code.  If you have two back-to-back shows on the same
channel, you can record both on the same DVB tuner, and pad both so that
they overlap.  To get this advantage with non-DVB cards, you could
pretend that they're DVB cards that only happen to have one subchannel
per channel.

So you can't record two different channels on a PVR-250 at a time, but
you can record the same channel twice from a PVR-250 at once.  [Again,
very nice for back-to-back shows on the same channel.]
