Glynor,
Thanks for pointing me in the direction there. I think I've got my series rules setup right now.
Just to clarify though, this will work for TV recorded by Media Center? I only ask because, as I poorly alluded to in #2 above, I did have a fairly basic rule setup to apply the "transient" tag already in place, but it didn't seem to apply to the TV Recordings made by MC. It works fine for other items imported from the directory though. I made another rule, more closely following some of the examples provided in the links to see if that helps, but I just want to make sure I'm being clear about what I'm trying to do here.
Thanks again,
Jon
