I would guess that isn't possible with any cheap machine, since decoding 8
720x576 MPEG-2 streams and encoding them to H.264/MPEG-4 AVC would require
quite much CPU power even if you used baseline H.264/MPEG-4 AVC options (in
that case image quality wouldn't be good). It might be easier to buy few
machines and split the tasks.
