I just switched to NFSv4 and now I still have to export each submounted file
system I only need a single top level mount on the clients.  All submounts
have the data I expect.

That along with idmapd made my life quite simpler.

I don't know if I'm going to regret going to v4 for other reasons

mounts on server:
/dev/sda3 on /myth type xfs (rw,noatime,allocsize=512m)
/dev/sdd1 on /myth/tv type xfs (rw,noatime,allocsize=512m)
/dev/sdb1 on /myth/tv2 type xfs (rw,noatime,allocsize=512m)
/dev/sdc1 on /myth/tv3 type xfs (rw,noatime,allocsize=512m)


/etc/exports on server:
/myth           192.168.1.91/32(rw,no_subtree_check,nohide,fsid=0)
/myth/tv        192.168.1.91/32(rw,no_subtree_check,nohide)
/myth/tv2       192.168.1.91/32(rw,no_subtree_check,nohide)
/myth/tv3       192.168.1.91/32(rw,no_subtree_check,nohide)

fstab on clients:
mythtv:/        /myth           nfs4 intr,rsize=8192,wsize=8192,timeo=14 0 0
