Hmm...so I imported the file to iTunes and now I can't figure out where iTunes put it! Anyone know if there is a general place where iTunes puts imported files?
Well, on a Mac in iTunes it would be treated as a music file, it won't make it part of the podcast list.
In iTunes, I suggest selecting the Music playlist under the LIBRARY heading.
This will show you all of the music in iTunes.
Then order it by name, and look for it to start with 'roundtable'
Alternately, you can sort it by date added, by selecting the 'date added' column. If you don't see the 'date added' column, you will need to add it to the view. Do this by going to the View menu, then selecting "View Options..." This will display a dialog box, and you need to check on the 'Date Added' field.
Once you have it sorted by 'date added' the last import should be at the top (or bottom depending on the direction of the sort)
Still don't see it in the ITMS Podcast Directory.
