I'm using cifs not smb, which doesn't support the ttl option. However,
it seems using the directio option fixed LiveTV, got rid of the ~10
second channel changes that I had with NFS and still keeps the recording
screen nice and snappy.

AFAIK, NFS in newer kernels also allows using directio although I'm not
sure if it's exposed in the same way as it is under CIFS. Probably worth
investigating if you want to stick to NFS, but there are certain Samba
features I need/want to abuse(mainly symlink masking, useful if the
links point to files outside of the normal export) so I'll be sticking
with CIFS for now.
