Charged 1.81€ above and beyond movie rental fee: Any idea why?

Above the rental charge, and a day before the charge was billed, our credit card was billed 1.81. I'm not he most patient websurfer but I did look all over and didn't find any reference to this fee. Can someone inform me about this (I hesitate to think it was iTunes' mistake -- ha!)?

Another question, since this was our first movie rental. After starting the download and the note tha it would take 5 hours to download, the 48 hour rental time began to count down -- even while we were to wait 5 hours! Is that fair?

Thanks!

Joseph
