I enjoy Tartan TV every chance I can.
My biggest complaint about SCETV (South Carolina PBS) is that they will Interrupt Tartan TV every chance they get.
Anytime they want to air something else they will bump Tartan TV.
They also seem to repeat the show a little too often (at least this season). The one with Loch Ness aired in January as well. They should show some of the older shows and mix it up a little. Just this year they seem to only be going back to 2005 series. Before they had access to shows for 3 seasons, which was excellent since most of their shows are not time sensitive.

Another wonderful show airs right before Tartan TV is
Out of Ireland. Watching this will keep you updated on the latest happenings
with Ireland and it's people. Not much on kilts here but a great show
to broaden your horizons.
