I will do some research tonight on this.  I have 5.0 at home and 7.0
here at work.  

I am glad to hear of the usb possability as the newer computers have a
scarciety of serials.  I have successfully downloaded the rdio but have
never been successful in uploading it from the pc after I make
modificaitons in the excel sheet.  I guess I do not do it enough but
with about 10 new tv channels here it might be nice to add them the easy
way rather than from the radio.  Later.
