OK, taks acepted :-)

It's the least I can do for all the time people have spent helping me.

OK, I think I'm going to go ahead and label all the vtapes/physical tapes, 
and then work on this, as it will minimize the variables. Seems reasonable,
as it just adds a bit of overhead to the inital setup.

I'll work on it next wek, then post the HOWTO here.
