Are you using software RAID? Are you on a budget? If so then you can use just two drives total (one per machine), assuming you're willing to leave the playback machine shut down when you go to fetch new shows. Configure both drives with normal Linux and swap partitions and install your favorite distro on each. Then put both drives in one machine and build a mirror array using a large partition from each drive (so they'll have the same serial number). Then split the drives and run both machines in "degraded mode". You can do anything you want on the playback machine while the recording machine fills up the RAID partition. When it's time to copy the data, tell the RAID on the playback machine that the partition is dirty and then shut down and pull the drive. Put the drive into the recording machine and tell it to "hot add" the dirty partition. It will mirror the recording partition onto the playback partition. Now shut down, pull the drive and return home. Your machine should mount the refreshed drive as the recording machine marked it clean again. Rinse and repeat. Since your MySQL database is also on the mirror, your MythTV menu should have all the correct show information.
