I only own a handful of streaming purchases at this point, so don't feel much need to catalog them at this point.

You could always create a "custom category" and add them manually within the Profiler program.

Best advice is to download the same title from Invelos  you saw on streaming.. ( doesn't matter at this point the exact upc code .. ) and then add 'said title'  to your wish list  and in the studio menu -category I add the option of  i.e. amazon or net flicks, showtime , HBO etc  etc.,  and then add the exact date i saw the title..
and of course depending on the title  if its really good ( and the day may come)  you would add that title to your library rate it accordingly ..

There are many times if a title is repeated months later on another channel and you can't remember if you saw it .. this is the best way to bring that up ..

... I also use this method of watched  if I'm sitting in my office and say.. Lawrence of Arabia is playing in HD on your favorite movie channel.. and you watch 60% of it ..  I'll mark it as being watched on that day.. just because I didn't take out the blue ray/dvd  of the same title and play it in my player doesn't  mean It can't me marked as "watched"  ...
