The mdadm tools will build arrays out of partitions, so you can 
divide up your disks to cover all the bases.  For example, if you 
only have two physical drives, you could create a RAID-1 array using 
/dev/hda1 and /dev/hdc1 (making /dev/md0) and install the root 
filesystem on it.  You would then create a RAID-0 using /dev/hda2 and 
/dev/hdc2 (making /dev/md1) for the recordings.  LILO will install 
and boot on RAID-1 as long as there is only two disks.  Now if either 
drive dies, all you lose is the recordings.
