Tough to answer. It'll obviously add more load because you're
recording more programs, but the added load from multirec
should be less than using two separate tuners. My changes
work like the DVB multirec: A single stream is read from the
network and dispatched to whatever recorders are listening to it.
I've got an old 3.2 GHz Pentium 4 system with 3 GB Ram,
a raid5 media volume, one HDHR and two pcHDTV-3000 cards.
For my testing I ran 3 recordings on all 4 tuners (12 recordings at once)
and it worked fine.
